10.4 Modes
A standard screen can be used to set the OP modes Online, Offline, Down-
load and Loop-Through.
In Online mode, there is a logical link between the OP and the PLC, or the
OP attempts to establish a link. The OP cannot be switched to online mode
by a PLC job.
In Offline mode, a logical link does not exist between the OP and the PLC.
The OP does not even attempt to establish a link.
In Download mode, data is transferred from the PU/PC to the OP. In this par-
ticular instance, a logical link does not exist between the PLC and the OP.
The OP cannot be operated while data is being transferred.
While the OP is being commissioned, troubleshooting or optimization of the
PLC program is often necessary. For this purpose, the PU or PC can be con-
nected to the second interface of the OP in Loop-Through mode. This way it
is possible to communicate between PC/PU and the PLC through the OP. For
the restrictions which have to be taken into account in Loop-Through mode
refer to section 15.5.
Jobs from the PLC to the OP can be initiated only when the OP is working in
normal Online mode or switched to Loop-Through mode.
To set OP modes, proceed as follows:
1. Choose the standard screen System
→
OpMode.
2. Set the mode you require by means of a symbolic input.
3. Terminate the function call.
You will find further information on OP modes in Chapter 16 of this manual.
