2.2 Controlling and monitoring
The HMI system used in this case is an OP3 or alternatively a TP170A.
Only a short overview is given here on operation. A detailed description on
operation is given in Chapter 6.
The HMI page contains a view on each block in the S7-CPU. Inputs for the
respective block are made via this view. The variables in the HMI system
are connected with the correct memory space in the S7-CPU, so that inputs
are at the correct location and can be evaluated in the S7 program.
Note
Information on setting the time in the HMI system via the S7-CPU or for setting the
S7-clock via the HMI system are given on the
ProduktSupportSeiten
[ProductSupportPages] under Entry ID 944136 (OP3) or Entry ID 2383397
(TP170A).
