Rule #1: If condition is equal to “(AI-0 > 5.0V) OR (AI-1 > 8.0V)”, the
“Flag-0” is automatically “ON”. Again, configure the reverse way in the rule
#2: If condition is equal to “(AI-0
≤
5.0V) AND (AI-1
≤
8.0V)”, the “Flag-0”
is automatically “OFF”. In this meantime, the local internal flag, that says
Flag-0, on the module can be mapping to remote digital outputs on different
destination modules via. peer-to-peer I/O activity.
The maximum I/O logic rules support up to 16. Each rule can support up to 4
different conditions and 4 different actions. There are 16 internal flags (i.e.,
auxiliary channels) on each module. The data type of internal flags is digital,
meaning its value is either logic True or logic False. It allows you to choose
these internal flags as input for condition rule as well as these flags as output
for action state. Therefore, you could easy to use these internal flags to
implement logic rule in cascade mode and mirror these flags to/from the
remote modules via peer-to-peer I/O activity.
The supported conditions and actions are as below:
Condition

After completing all configurations for I/O logic rule, click “Save” button in the
bottom of the Logic Rules area. All the mapping configurations will be flushed
into flash memory on the module. In order to extend the flash memory life, it is
strongly recommended that you should save all configurations together at one
time instead of saving individual setting many times.

Go to “Peer to Peer I/O” page.
With peer to peer I/O activity, input channel status on one module could be
actively updated to specific output channel on another module over the
existing Ethernet connection. The above data exchange will be transferred
automatically without any controller or programming needed.
