Configuring the HSIO Mode
If you have chosen a mode suited to the high-speed I/O needs of your application, we’re ready
to proceed to configure the PLC to operate accordingly. In the block diagram below, notice
the V-memory detail in the expanded CPU block. V-memory location V7633 determines the
functional mode of the high-speed I/O circuit. This is the most important V-memory
configuration value for HSIO functions!
The contents of V7633 is a 16-bit word, to be entered in binary–coded decimal. The figure
below defines what each 4-bit BCD digit of the word represents.
Bits 0 – 7 define the mode number 00, 10.. 60 previously referenced in this appendix. The
example data “0050” shown selects Mode 50 – Pulse Catch (BCD = 50).
Configuring Inputs X0 – X3
In addition to configuring V7633 for the HSIO mode, you’ll
need to program the next four locations in certain modes
according to the desired function of input points X0 – X3.
Other memory locations may require configuring, depending on
the HSIO mode (see the corresponding section for particular
HSIO modes).
