Hi,
You can remove IO modules starting only from last module.
The M90 and M91 can be holed up to I/O Expansion Modules. Note that Jazz controllers are not currently compatible with I/O Expansion Modules.
1. Click the Hardware Configuration icon on the Standard toolbar.
2.
Click the Digital or Analog tab,
according to the module you are connecting.
Click the appropriate I/O module. The selected module will appear on the Model Expansion bar. You can also drag and drop a module onto the bar.
Continue adding I/O expansion modules according to your expansion configuration.
Click an I/O expansion icon in the Model Expansion bar. The I/O Details window opens.
Click the appropriate Inputs / Outputs to enter the desired descriptions.
To remove an I/O Expansion Module from the bar, right-click it and select Remove.

If your application does not require that you use all of the I/Os on a particular I/O expansion module, do not select the unused I/Os when you configure the module. Selecting unused I/Os may add to the program's scan time |
1. Double-click an I/O expansion icon in the Model Expansion bar. An I/O Details window opens.
Click the appropriate Inputs / Outputs to enter the desired Addresses and Symbols.
The Addresses and Symbols appear in the I/O Details window.
Note: If your application does not require that you use all of the I/Os on a particular I/O Expansion Module, do not select the unused I/Os when you configure the module. Selecting unused I/Os may add to the PLC's scan time.
Inputs and outputs located on I/O expansion modules that are connected into an M90 OPLC are assigned addresses that comprise a letter and a number. The letter indicates whether the I/O is an input (I) or an output (O). The number indicates the I/O’s location in the system. This number relates to both the expansion module’s position in the system, and to the position of the I/O on that module.
Expansion modules are numbered from 0-7 as shown in the figure below.
The formula below is used to assign addresses for I/O modules used in conjunction with the M90 OPLC.
X is the number representing a specific module’s location (0-7). Y is the number of the input or output on that specific module (0-15).
The number that represents the I/O’s location is equal to: 32 + x • 16 + y
Example
Input #3, located on expansion module #2 in the system, will be addressed as I 67, 67 = 32 + 2 • 16 + 3
Output #4, located on expansion module #3 in the system, will be addressed as O 84, 84 = 32 + 3 • 16 + 4.
EX90-DI8-RO8 is a stand-alone I/O module. Even if it is the only module in the configuration, the EX90-DI8-RO8 is always assigned the number 7. Its I/Os are addressed accordingly.
Example
Input #5, located on an EX90-DI8-RO8 connected to an M90 OPLC will be addressed as I 149, 149 = 32 + 7 • 16 + 5
Hi,
You can remove IO modules starting only from last module.
what if the remove is grayed out?
