Each of these options would need the address set up under the option menu before they would communicate. Pressing the "OPTION" key (number 7) and then using the up arrow to get to the proper option (either serial, Profibus or RIO), then using the enter key to go through the settings. This is where you would make changes to the settings as well.
When you have two units and one is having a problem, swapping the units is a good way to determine if the problem is with the unit or some other portion of the system. In this case, there may be a simpler way. You have one unit that will not respond to the keypad. If this is the case, you cannot get into the menu to see the address, so it is more difficult to swap units. There is NOT another part of the system that would cause the unit to not respond to its keypad. A simple test would be to power the unit down, disconnect everything from the unit except power, and power the unit back up. If the unit still does not respond to the keypad, then it is a problem inside the unit.
The suggestion here would be to remove the Secure Memory Module (SMM) from the bad unit. To do this, power the unit down and remove the SMM from the unit and then power the unit back up. This will allow you to determine if the unit has a simple corruption in its memory that is giving you problems or if it is a hardware problem. If the unit now responds to the keypad, (without the SMM) then it was a memory corruption problem and clearing the memory should solve the problem (instructions below). If the problem is still present, then the unit would need to be returned to the factory for repair.
NOTE: Do not "hot swap" SMM's or your option data may be erased. Make sure the power is off when you install your SMM.
Clear memory on the bad unit. To do this, follow these steps:
Power unit down.
Remove the four screws holding the back plate onto the unit.
Pull the boards out of the case.
Find the set of dip switches labeled S2 on the bottom board (Power Relay Board). This set of switches is located about 1/2 way down the left side of the board as you look at it from the back of the unit.
Turn switch #8 of S2 to the on position. (#8 is the switch closest to the edge of the board)
Return boards to the case and power up the unit.
The display will show a normal initialization, then stop at a display of TGCLRD.
At this time, power down the unit, remove boards and return switch #8 to the OFF position.
Re-assemble the unit and power up. Unit should be in normal operating condition.
NOTE: Clearing memory on the unit will return it to factory default settings. A new setup and calibration will need to be done.
If the original unit still has a problem with responding to the key pad after removing the SMM, then you could find the address of the unit by putting the SMM from the bad unit into the second unit (remove power before removing or installing the SMM). Once you have the SMM in the other, good unit, go into the option menu and read the address and note this for future use. You may want to leave this SMM in this unit when you swap the two units, as this SMM will have all your settings in it already.
If the problem is a corruption in the memory, then there would be no way to get the address from the unit and you would need to contact the person that set up the system to find out what the address was. Once you determine what the address was, it should be noted somewhere for future reference.
