Tecnomatix Interlock Robot Signals (Fanuc)

Customer is working with actual Fanuc Robot Programs. 
They want to set it up so Robot 1's DO[101] turns on Robot 2's DI[101]. 
Is there an easier way or some built in way of doing this than the following? 

1. Create Robot Signals for both R1 and R2 
2. Create Logic Blocks to interlock/turn on the other robots signal. If R1_DO[101] turn on R2_DI[101]

They don't want to use special OLP commands. The goal is just be able to just load in updated robot programs and not have to change/modify them (add special commands). 

Solution

There is no other way than to create a LB that does this signal mapping, if you do not want to instrument the program with ToRobot special signals commands (# Destination, # SendSignal).
