Product Manual Excerpt

GENERAL DESCRIPTION The High Speed Counter is an intelligent I/O module and can be utilized in an I/O rack, or in any of the I/O slots in a Mode1 60 CPU, to solve a wide variety of position and velocity measurement/control applications where the frequency of incoming pulses is too high to be handled directly by the Series Six CPU. Features and Benefits for this module are summarized in Table 1. This microprocessor based counter is capable of receiving count pulses from quadrature encoders, digital tachometers, and mechanical or transistor switches Input voltage levels are jumper configurable to accept TTL Single Ended, TTL Differential, or 10-30 VDC signals. Four open-collector transistor outputs are provided for real time response independent of CPU scan time. Each output can sink up to 250 ma at voltages up to 30V. Individual pull-up resistors are also provided. The module can accept pulse rates of 50 KHz per channel. The accumulated count is stored as a 24 bit 2 s complement number giving a counting range of -8,388,607 to + 8,388,607. A total of 12 software preset registers are supported by the High Speed Counter module. Four of these presets control the four real time outputs while the remaining eight can be used in CPU relay logic. Each preset value can be individually set by the CPU. It is then continuously compared to the accumulated count by the modules microprocessor. The user can determine the sense of the comparison, selecting between having the output turn on when the accumulated count is less than (<) or greater than or equal to> the preset value. User logic in the CPU can individually set the four real time outputs to be enabled/disabled, and/or latched/unlatched. Additional capabilities allow the user to enable/disable counting, select count direction, reset the accumulated count to a predetermined value, or dynamically change any of the I2 software preset registers. Since this intelligent I/O module resides in the Series Six I/O structure, multiple counter modules can be utilized. Each counter will use 32 Input and 32 Output addresses by which the CPU downloads preset and mode select data and by which position and status data is received.

Before installing the 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 32 consecutive bits in the appropriate Input AND Output Status Tables of the CPU. For specific DIP switch settings, refer to Figure 1. You should also set the circuit board jumpers and dip switch to configure the module for your particular application. Refer to Figure 2 for description of all user settings. We recommend that you use the extraction/insertion tool furnished with your 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. You can then secure the faceplate to the rack using the thumbscrews at the top and bottom. Refer to Figure 3 and 4 for typical user output connections to this module. Figure 7 shows the general internal design for the four output circuits, while Figures 5 and 6 contains the general internal design for the input circuits. WARNING Voltages from user field devices could 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. If the CPU RESET signal is high, the counter will continue to function, except outputs 1 thru 4 will be forced off regardless of their previous state. When the CPU once again becomes operational, the four outputs will return to their conditional state as determined by the enable/disable and latch/unlatch bits and the preset comparison state. If the CPU RESET signal is high, the counter will continue to function, and will retain full control over its four outputs. FIGURE 2.
