Publication 1734-UM015A-EN-E - November 2009
Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetworx for DeviceNet 57
The 1734-IE4C has an input message that looks like this:
To use the analog data from channel 2, click to place an analog bit input
on the function block sheet in the DeviceLogix editor.
Channel 2 is mapped to Word 2. Select this as shown below. For help on
mappings, see
Appendix A .
To use the Over-range bit of channel 1, you can use "bit input" I/O tag and
select Peer#1, byte 9, bit 7.
Again, it is best to use the Peer Connection Status bits (Peer#1 Data Valid and
Peer#1 Exists) to validate the data before using it.
