Product Manual Excerpt

ANALOG OUTPUT MODULES GENERAL DESCRIPTION The Analog Output module is available in three versions: unipolar, bipolar and current. The unipolar module delivers output voltages in the range, 0 to + 1OV. The bipolar module provides output voltages of either polarity, -10 to +l0V. The current module delivers output currents in the range, 4 to 20mA. The Analog Output module features and benefits are summarized in Table 1. In operation, these modules receive from the CPU twelve bits of binary output data as well as a binary number indicating which channel is to be accessed. The module functions as a digital-to-analog (D/A) converter, delivering the proper output voltage or current to the designated channel. This output level is maintained until the channel is accessed again. Each module contains an address decoder and an optoisolator, along with D/A and output amplifier circuitry. On the two voltage-output modules, an internal power converter delivers output levels that are isolated from the I/O bus. On the current-output module, the user can derive output power from this converter, or choose to provide an external power source, reducing the load on the power supply in the I/O rack. An LED indicator displays the status of the module. Individual channels can be reassigned (with on-board jumpers) to function as unipolar, bipolar or current outputs. Refer to Figure 1 (next page) for Analog Output module specifications.

Before installing the Analog Output module, the dual-in-line-package (DIP) switches immediately behind the card slot on the rack backplane should be set to reserve a group of 16 consecutive bits in the appropriate Output Status Table of the CPU. For specific DIP switch settings, refer to Figure 3. Use the extraction/insertion tool furnished with the CPU to remove or install the circuit board. With the board in place in the rack, the edge connector on the faceplate should be slipped 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. = Switch in OPEN Posi ion (Depressed to the Left) Switches No. I and No 2 should be in CLOSED Position FIGURE 3. DIP SWITCH SETTINGS NOTES 1. A group of 16 consecutive I/O points are required for this module to communicate with the Output Status Table. Each of the four output channels in this module uses these same 16 I/O points for the loading of data. Each of the output channels has its own memory contained within the module. All channels being used will have a constant output whether it is updated every scan or every 10 scans. Each time a total I/O scan is executed the output programmed by the user logic program will be updated. Refer to the Programming Manual, GEK-25362, for more detailed instructions. 2. Using the CPU Extended Functions, the user can elect to output repeatedly the same channel or scan up to all four channels in sequence at a much faster rate than the normal I/O scan rate or output up to all four channels in sequence at a much faster rate than the normal I/O scan rate. This is accomplished by programming a \\\"DO I/O\\\" function or functions during the normal user program. Refer to the Application Guide, GEK-25365, for more detailed instructions. 3. It is the responsibility of the user to program a store in a register of the data that has been or is going to be output to the various output channels. These registers will be the data used in the logic program as the output table will have data about only one of the output channels in it. 4 Ref. 70.152 Analog Output Module GEK-83526 ELECTRICAL INSTALLATION The Analog Output modules can be used and wired to in many different ways. A symbolic Analog Output circuit is shown in Figure 4. Typical user output connections when using a 0 to + 10V or -10V to + 10V Analog Signal receiver refer to Figure 5. For the 4 to 20 mA Analog Output module, the channels can be connected for internal or external common source operation depending on the setting of the circuit board jumper. Alternatively, any one or more individual channels can be connected with its own external source. Be aware that all common (COMM) terminals are connected together inside the module. To minimize capacitive loading of the the outputs, twisted-pair cables should be used for output connections wherever possible. Refer to Figure 6 for typical user output connections. For other types of Analog receivers refer to Instrument Society of America Standard IS A-550.1 for guidance. FIGURE 5. TYPICAL VOLTAGE OUTPUT CONNECTIONS NOTES 1. Maximum Loading is 5 mA for full voltage output. 2. All four outputs on this module are single ended and must be referred to the same user side common which is isolated from Series Six ground. 3. All COMM terminals are connected together internally to the module. 4. If multiple destinations are connected to the same output module their reference points (common) must be connected together and be at the same voltage. COMMON IC NON-FLOATING USER INPUT CIRCUIT OR SIX ANALOG INPUT MODULE NOTES ircuity 2. The loading of the 4 to 20 mA module should be in n 1017 accordance with ISA-S50.1 Transmitter Standard ust be Class 2L when the module is using the internal es Six loop power supply as shown. SIG A FIGURE 7. TYPICAL OUTPUT CONNECTIONS FOR 4 TO 20 mA OUTPUT USING EXTERNAL POWER SUPPLY NOTES 4 TO 20 mA CURRENT OUTPUT TO FLOATING USER INPUTS ONLY A. If damage could be caused to user input circuits because Signal A and Signal B inputs are from +23V to 42V above common (depending on the external supply), then the user must select other truly floating input receivers that can withstand this voltage differential. B. The loading of the 4 to 20 mA module when using an external power supply should be in accordance with ISA-S50.1 Transmitter Class 2U or 4U data. This module is in compliance with or exceeds this specification. C. Individual external supplies or common external supplies may be used on the same output module if the commons of the two supplies are at the same potential and may be connected together. D. All points marked \\\"COMM\\\" on the output module are tied together internally. Caution must be used when connecting user commons to the same output module. 8 Ref. 70.TMP.28 Analog Output Module GEK-83526 DIGITAL DATA FORMAT Bit 1 corresponds to the lowest output number in the group of 16 outputs reserved for the module; Bit 16 corresponds to the highest output number in this group. Bits 13-14: Channel Number: 2-bit binary number which determines the number of the channel (1 to 4) being accessed. Bit 14 is the MSB. Bits 15-16: Not used: (May be in either a HIGH or LOW state.) Bits 1-8: Data: Eight least significant of the twelve bits of data. Bit 1 is the least significant bit (LSB). Bits 9-12: Data: Four most significant of the twelve bits of data. Bit 12 is the most significant bit. For the bipolar (-10 to + 10 V) module, Bit 12 functions as a sign bit. The twelve bits of data should be in straight binary form for positive output values, or in 2\\\'s-complement form for negative values. For the Bipolar (-10 V to + 10 V) module, bit no. 12 functions as a sign bit. OUTPUT STATUS TABLE DISPLAY Two consecutive I/O addresses are required to write all 16 bits of information associated with each channel. A single channel is normally accessed during each sweep. The channel number is determined by the CPU, under control of the user program. Analog Output Module GEK-83526 CALIBRATION PROCEDURE Required equipment: Voltmeter - 5 digit 250 ohm Precision Resistor Calibration Connector (IC600MA508A) Small screwdriver with approximately 3 inch insulated shaft. Calibration of the Analog Output module should be performed every 90 days. For maximum accuracy the module should be calibrated at the normal ambient temperature which occurs in operation. 1. SET UP: Loosen the thumbscrews, remove the faceplate, taking care that the field wiring is not disturbed. Place the calibration connector on the front edge of the module. For the 0 to + 10 V or the -10 V to + 10 V module connect a Digital Voltmeter (DVM) between the terminals of the calibration connector as listed in the V column for the first channel in Table 2. For the 4 to 20 mA module, connect a 250 ohm precision resistor in parallel with the DVM, using the terminal numbers in the I column of Table 2. Be sure that the circuit-module jumper is set for the internal loop supply. Display the Ouput Status Table on the screen of the Program Development Terminal (PDT), with the cursor on the lowest output number assigned to this module by the DIP switches. Shift the display to hex format, obtaining a display of four hexadecimal digits corresponding to the 16 Output Status bits used by this module. 2. LOW END: Using the PDT keyboard, enter the four hex digits shown in the LOW END column of the Calibration Table into the Output Status Table. Note that the first digit assigns the channel number (1 to 4). Adjust the Offset Pot (Refer to Figure 2) for this channel until the DVM reads the voltage shown in Table 3. 3. HIGH END: Using the PDT keyboard, enter the four hex digits shown in the HIGH END column of Table 3 into the Output Status Table. Adjust the Gain Pot (Refer to Figure 2) for this channel until the DVM reads the voltage shown in Table 3 . 4. FINE ADJUST: Repeat steps No.2 and No.3 until no further change in either pot setting is required. 5. OTHER CHANNELS: Change the connections according to Table 2, and repeat steps No.2, No.3, and No.4 for channels 2, 3 and 4. TABLE 2.
