Cascade counting requires that a jumper be configured. You can configure the 16-bit counters to count in one of the following modes: Retriggerable one-shot.

  • Page 35: Retriggerable One-Shot

    Retriggerable The retriggerable one-shot mode generates an output that is On (high), from One-Shot the first clock after a trigger, and remains On until the preset number of clocks have been counted down to zero. The output is On for the preset number of clocks.

    Setting the To program the HSCE module, set bit WY20.01 (see shaded bit in Program Bit Table 5-13). Set bit WY20.01 by writing the programming values to WY19 and WY20 word locations. After you set the program bit (WY20.01), the indicator is off.

  • Page 97: Using Gated Counting

    Using Counters 1 and 4 In the following counting modes, the 24-bit counter counts up or down on each input pulse received as long as INHIBIT and RESET are low. Using Gated In gated counting, the current count words are continuously updated by the Counting module and read by the PLC on each scan.

  • Page 98: Using Time Sampled Rate Counting

    Using Time In time sampled rate counting, the counter counts the number of input Sampled Rate pulses during a given period. You select the sample period (1 ms, 10 ms, Counting 100 ms, or 1 second) by setting the appropriate bits in the preset word and by setting the control jumpers to [Internal Period] and [Reset-and-go].

    Using Counters 2, 3, 5, and 6 Using Binary Up or The 16-bit counters can be configured as binary counters. The count value Down Counting wraps about the count value of zero and continues counting in the upward or downward direction. You select the count direction in bit WY20.07 for counters 2 and 3, or WY20.08 for counters 5 and 6.

  • Page 100: Using Divide-By-N Mode

    Using Divide-by-N Configure the counter for Divide-by-N mode as follows: Mode Preset: Divide-by-N counting sets the count value to zero on the first valid clock pulse. The clock increments the count value until it is 65535. At that time the output turns On and remains On for one clock period. The preset (0) is loaded into the counter, counting continues, and the output pulses each cycle.

  • Page 101: Cascade Counting Applications

    Cascade Counting Applications 32-Bit Cascade The 32-bit cascade counting mode cascades the output of one channel’s Counting 16-bit counter (3 or 6), in Divide-by-N mode, into the clock input of the other 16-bit counter (2 or 5) of the same channel. When both channel counters, 2 and 3 or 5 and 6, are configured in Up Counting, Divide-by-N mode, the module assumes 32-bit cascaded counting has been configured and converts the count value by adding 1.

    Prescale Counting Applications 16-Bit Prescale The 16-bit prescale 16-bit counting mode cascades the output of one 16-bit 16-Bit Counting counter, in Divide-by-N mode, into the same channel’s other 16-bit counter. This counting mode functions the same as 32-bit cascade counting described in Section A.3, Cascade Counting Operations;...

  • Page 103: 16-Bit Prescale 24-Bit Counting

    Prescale Counting Applications (continued) 16-Bit Prescale The 16-bit prescale 24-bit counting mode cascades the output of one 16-bit 24-Bit Counting counter, in Divide-by-N mode, into the A input of the same channel’s 24-bit counter. The B input jumper is set for Up Count Only. By using the repetitive nature of Divide-by-N mode, the output of the 16-bit counter pulses the rollover signal, at every count of 1, into clock input A of the 24-bit counter.
