compatible with the AEG A120, A250-controls
immediately ONLINE with both interfaces to the plc
can be operated by all original and compatible programming devices
all PG connections are the same as a AEG A120, A250
all connections and operating elements are at the front of the device
module which controls all the device functions and the voltage supply and which resets the
device in case of failure

11.4.1 Take notice
The usage with a A120 and with a MICRO AEG (with adapters for the MICRO AEG, but not
the TSX MICRO) works correctly. At the work with a A250, the PG can try to conform the
PLC. The PLC make changes inside and works with different baudrates for a short time. The
MUX will may lost the communication, but will find it a few seconds later. The PG will show
an error message. In fact, please confirm the function load program into the PLC´ without the
MUX.
If two operation panels are connected to the PG-MUX, both must be differently
parameterised, in case of that the operation panels haven’t the same FW´s and DB´s. If the
FW´s and DB´s are the same, the PLC can not distinguish from what OP the data was
transferred. That problem doesn’t appears when you use different FW´s and DB´s.
You should generally enter a `time-out` into your OP (if it is possible), because if a PG
transfers a large DB (for example), the OP must wait for the next conversation with the PLC.
If you increase the time-out, the OP waits for a longer time, can’t go into the ´time-out´. A
good time is 3-5 sec.
