Introduction

This manual describes how to migrate from 1756, 6-channel isolated analog I/O modules to their newer 8-channel isolated counter parts in the 1756 analog I/O platform.

In Emulation mode, when a forward open containing configuration data is sent to the 8-channel module it can accept it and respond as if it were a 6-channel module. After the connection is established, all data (input/output) will be sent to or from the controller in the same format and tag structures as a 6- channel module. You can directly replace a 6-channel module with an 8- channel module with no I/O tree modifications or program changes with this method.

When the 8-channel module receives configuration data for a 6-channel module, it takes that information and formats it to replicate the configuration data of an 8-channel module. The 8-channel module then scans its 8-channel module firmware but reformats all input or output data to match the 6-channel module.

Additionally, the 8-channel module is internally behaving as an 8-channel module because most of the firmware has not changed. The difference in 8- channel module firmware is that in Emulation mode configuration, input data, and output data is reformatted to match the appropriate 6-channel module.
