*Bit 2 of Time of day clock control word must be set or the PLC will not read clock
values definitions specified. Write either a 4000hex or 6000hex into the first
location allocated for the PLC time of day clock. Refer to the MODSOFT
programming manual for more information on the time of day clock usage.
☞ Note: The PLC time of day clock is read once at power up from registers 4x+1 through
4x+8. The module’s internal clock chip is synchronized with the PLC clock at
this time. After power up, the module clock is synchronized with the PLC clock
at least once a day. (See Section 4.2 for more details.)
The ACI 052 00sc multiplexes 32 channels of data into four groups
