Communicate with Devices on a ControlNet Network Appendix B
Note that the tags for the analog module (‘remote_flex:2:I,’ ‘remote_flex:2:O,’
and ‘remote_flex:2:C’) are not alias tags.
Direct Connections
If you choose None for the communication format to the communication device,
the software assumes that you want a direct connection for each I/O module
connected to that device. The software creates slot-referenced tags for each
I/O module, but not for the communication device.
Analog modules require direct connections to operate. Do not use the element
of the rack-optimized array tag to control the analog module. Use the
individual, slot-referenced tag.
