Configuring The Hsio Mode; Configuring Inputs - Automationdirect.com DL05 User Manual

Configuring the If you have chosen a mode suited to the high-speed I/O needs of your application,
HSIO Mode 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 chapter.
The example data "2050" shown selects Mode 50 – Pulse Catch (BCD = 50). The
DL05 PLC ignores bits 8 - 15 in V7633.
Configuring In addition to configuring V7633 for the
Inputs X0 – X2 HSIO mode, you'll need to program the
next three locations in certain modes
according to the desired function of input
points X0 – X2. Other memory locations
may require configuring, depending on the
HSIO mode (see the corresponding
section for particular HSIO modes).
