115 VAC Input Module March 1988 32 Inputs per Module General Description The 115 VAC Input module detects bipolar AC voltage supplied by, and controlled by, the user. The features and benefits of this module are summarized in Table 1. A module contains thirty two inputs, divided into four groups (A, B, C, D), each group sharing a neutral circuit (A corn, B corn, C corn or D corn). and a Schmitt trigger (one-shot), which fires to indicate that an AC voltage in a specified range has been detected. An active input circuit is indicated by a Light-Emitting Diode (LED), visible through a lens on the faceplate. Refer to Table 2 for the I15 VAC Input module specifications. An input circuit contains an AC divider, a noise filter to reduce common mode transients, an opto-isolator, Table 1.

USER ITEMS 115 VAC Input Module 3 GFK-0174 InstalIation The 115 VAC Input module can be installed in an I/O rack or the I/O rack section of the Series Six Plus Central Processor Unit (CPU). Follow these steps: 1. 2. 3. 4. Set the Dual-In-Line-Package (DIP) switches directly behind the card slot on the rack backplane to establish the correct correspondence between the first group of 8 input terminals on this module and the first of four consecutive groups of eight input numbers in the user program. For further information on I/O DIP-switch settings, refer to the Installation Section of the Series Six Plus Programmable Controller User s Manual (GEK-96602). Use the extraction/insertion tool furnished with the Series Six Plus CPU to insert (or remove) this module in the card slot. Guide the faceplate over the circuit board so that the terminals near the bottom of each are mated; secure the faceplate to the rack using the thumbscrews at the top and bottom. Refer to Figure 2. Connect one side of the user circuit to the appropriate input terminal (1 through 8). Circuits connected to inputs 1 through 8 of a group must have their opposite sides connected to the common for that group. Each input terminal can accommodate one No. 12 AWG wire. WARNING I Voltages from user field devices may be present on the faceplate terminals, even if the power supply in the I/O rack is off. Care should be taken when handling the faceplate of this module or any wires connected to it. *AC SOURCE A, f3, C OR D a42382 I I INPUT I MODULE 1 - a - - 2 I - - Figure 2.

GE Fanuc Automation North America, Inc., Charlottesville, Virginia Series S i x Programmable Controller GFK-0238A Communications Control Module Type 2 and Type 3 November 1988 General Description The Communications Control Module Type 2 (CCM2) and Type 3 (CCM3) are modules for the Series S i x PLC containing two communications ports, two switches, and four indicator Light Emitting Diodes (LEDs) for connection, control, and status of the module. The primary purpose of these modules is to provide a serial interface between the Series Six Central Processing Unit (CPU) and any intelligent device which can initiate communications based on CCM2 and/or CCM3 supported protocols and electrical interface requirements. Examples of intelligent devices which can be interfaced are: CCM2, CCM3, or I/O CCM Series Six modules 0 Host computer or microprocessor based device Process control system e Color-graphics terminal IC600CB536 IC600CB537 The Series Six Plus PLC with expanded microcode increases the number of user addressable I/O points. This feature allows addressing of channeled I/O points with the Series Six expanded instruction set. The I/O points can be accessed by both the CCM and the Remote Terminal Unit (RTU) protocol for CCM3, and the CCM protocol only for CCM2. CCM also supports addressing of the Auxiliary I/O Override table. Expanded user memory reference allows memory addressing up to 64k of the user logic memory. The expanded user logic memory is supported by both the CCM and the RTU protocol. Table 1. FEATURES AND BENEFITS FEATURES Contains two programmable communications interfaces. BENEFITS Permits a data link between Series Six and host computer, programmable terminals, and other intelligent devices. Accepts requests for Serial Communications from CPU user program. (If peer or master mode is selected.) On-board diagnostics and board fault indicator lights. Allow CPU logic to initiate and control the communication and data flow. Simplifies troubleshooting arid indicates correct data transfer. Direct interface with Operator Interface Unit (OIU). Allows for simplified operator inputs into process under control. QAB (Quick Access 1024 byte general purpose Buffer) Buffer data to minimize access time from an external device. Expanded memory Permits addressing of channeled I/O points, up to 64K user logic memory. 2 Communications Control Module Type 2 and Type 3 CCM2/CCM3 System Configurations The CCM2/CCM3 supports two types of system configurations, point-to-point and multidrop. In the point-to-point configuration only two devices can be connected to the same communication line. The communication line can be directly connected using RS-232 (50 feet, 15 meters maximum) or RS-422 (4000 feet, 1200 meters maximum). Modems can be used for longer distances. In the multidrop configuration more than two devices can be connected to the same communication line. One CCM2 or host device is configured as the master and one or more CCM2s/CCM3s are configured as slaves. A master is capable of initiating communications; a slave is not. There are three ways to connect CCM2s/CCM3s in the multidrop configuration: RS-422 direct, RS-232 using modems, and RS-232 using modems and microwave or radio transmitters. RS-422 Direct: This method can be used when the maximum distance between the master and the last GFK-023 8A slave does not exceed 4000 feet (1200 meters). This distance assumes good quality cables and a moderately noisy environment. A maximum of eight slaves can be connected using RS-422 in a daisy chain or multidrop configuration. The RS-422 line may be of the 2-wire or 4-wire type. RS-232 Using Modems: This configuration is used for long distance communications, primarily over telephone lines. The number of slaves possible is determined by the modem capabilities. RS-232 Using Modems and Microwave or Radio Transmitters: This configuration is used where cables cannot be used between modems. The FCC normally requires the use of single frequency transmitters with short transmitter-on times. Therefore, a warm-up delay for the radio transmitter must be added before each transmission. The CCM2/CCM3 keys the radio transmitter to warm-up and wait a short time before actually transmitting the data. The various time-out values for the communication protocol are increased to include the added delay. Table 2.

Belden -9184 Belden -9302 NEC -222PISLCBT At shorter distances, almost any twisted pair or shielded twisted pair cable will work. It should be noted that RS-422 requires that the transmitter and receiver ground be within a few volts of each other or damage to the transmitter and receiver may result. It is also noted that the twisted pairs should be matched so that both transmit signals make up one twisted pair and both receive signals make up the other twisted pair, If this is ignored, then cross-talk can result from the mis-matching which will affect the performance of the communication system.

FLASHING: Invalid configuration or invalid CPU number, 0 or greater than 90 for CCM slave mode, 0 or greater than 247 for RTU mode (CCM3 only). The configuration or the CPU ID must be changed and the module powered up again to recover. OFF: Board has failed power-up test indicating a hardware failure or the CCM failed to communicate with the Series Six CPU. I f the BOARD OK LED goes off as a result of a major CCM error, further information about the specific cause of the error can be obtained by toggling the front panel switch. When this is done, the 4 indicator lights will create one of the patterns shown in Table 3. - If it is a hardware failure then the CCM is inoperable and the LED will turn on again only after successful completion of the power-up test. s If at some time after a successful power-up there is a CCM/CPU communications failure, both the BOARD OK and the DATA OK LED will turn off. In this case additional information from the front panel LEDs cannot be obtained. Both LEDs will turn on again upon successful communications with the CPU. DIAG 1 STATUS DESCRIPTION ON: OFF: Passed powerup diagnostics. ON during normal operation. Cycles on and off during powerup then remains on. May change states when toggling Switch A or B. DATA OK (Serial Data Transmission Link) STATUS DESCRIPTION ON: FLASHING: OFF: Data transmission normal. The LED will flash as serial data is actually transmitted. Data transmission is incorrect for one or more of the following reasons. - Parity, overrun or framing errors. - Invalid header, data block, control character, or checksum. In these cases the LED will turn on again after a successful session has been completed between the Series Six and the external device, or if the module power is cycled. A CCM./CPU communications failure will cause this LED and the BOARD OK LED to turn OFF. DIAG 2 STATUS ON: OFF: DESCRIPTION Passed powerup diagnostics. ON during normal operation. Cycles on and off during powerup then remains on. May change states when toggling Switch A or B. Communications Control Module Type 2 and Type 3 7 GFK-0238A Installation General Before instaIling the CCM2/CCM3 in a CPU rack verify the position of the factory set jumpers (see Figures 1 and 2). Select the appropriate module function options by setting the on-board DIP switches (as required) per the coding shown in Tables 5, 6, 7 and 8. The CCM2/CCM3 module can be installed in a model Six Plus, 60, 600, or 6000 PLC. - In the Series Six 60,600, or 6000 PLC the second slot to the left of the CPU power supply is reserved for this module, and is the only position where the CCM2/CCM3 can be installed. - In the Series Six Plus PLC, slot 5 or 6 is reserved for the CCM2/CCM3 module. When slot 6 is used, set the backplane DIP switch package to all positions OPEN. NOTE The normal powerup operation with all backplane DIP switch positions set to OPEN is: All four LEDS powerup ON, next a BLINKING sequence, then all LEDS remain ON. An unpredictable LED powerup sequence results when the backplane DIP switch package is set otherwise. The ALU Module LEDS remain OFF. And, if a Workmaster is connected, a message No communications with the Series Six is displayed. Use the extraction/insertion tool furnished with the Series Six CPU to install or remove the circuit board. With the circuit board in place in the rack, guide the faceplate over the circuit board so that proper contact is made; then secure the faceplate to the rack using the thumbscrews at the top and bottom. The CCM2/CCM3 module obtains its ID Number from the Series Six PLC. Use the L o g i c m a s t e r software to set the correct ID Number in the Series Six CPU scratchpad. Since there are many combinations of devices this module can interface with and many ways to wire up these combinations only a few of the more common wiring connections are shown as follows: The pinout definitions for ports Jland J2 are shown in Figure 3. Direct connect from one CCM2 module to another CCM2 is shown in Figures 4 and 6. Direct connect from a CCM2/CCM3 module to a computer or process control system is shown in Figure 5. Wiring from a CCM2/CCM3 to a GEnet Factory LAN BIU is shown in Figures 8 and 9. Wiring for CCM 4-wire multidrop network is shown in Figure 10. Wiring for a CCM 2-wire multidrop network is shown in Figure 1 I. Wiring from a CCM2/CCM3 to an Operator Interface Unit (OIU) is shown in Figure 7.
