Notice
By default, PLC addresses are restricted to the address range of the smallest
PLC.
To remove this restriction if you are using a more powerful PLC and want to use
the addresses in ePS, you must increase the corresponding values in the trigger
DB (DB239 in ePS Standard) in DW8 for inputs, DW10 for outputs, DW12 for bit
memory, DW14 for timers, and DW16 for counters to the available address ran-
ges. You must then restart the PC on which the ePS client is installed.
Warning
Using the trigger DB with an increased address range can cause the PLC to shut
down when the higher addresses are used in ePS Network Services configura-
tions if this address range is not actually available to the connected PLC.
