<p>Here's the deal - we have two seperate buildings, each has a Contrologix backplane with a 1756-ENET module and a 1756 DHRIO module. Both DHRIO module channel A is configured as DH+ and there is a PLC connected to the DH+. We want to message data from PLC A, through one Contrologix gateway, to the other Contrologix gateway, to PLC B.

<p>Like so...
<pre>
DH+ ENET DH+
PLC A -------> CTL -------> CTL ------> PLC B
</pre>
<p>We need to know how to configure the 1756-ENET and 1756 DHRIO modules to support this setup. Any help will be appreciated.

<p>Thanks<br>
