"Command" (VB1700 1001) corresponds to the following IS:
●
"Execute command" (V1700 2001.0)
●
"Command execution error" (V1700 2001.1)
When a command > 0 is written, the job is started by the PLC. As soon as the HMI detects a
command > 0, it begins with the internal processing of this job and sets the command
(VB1700 1001) to 0.
PLC waits until the acknowledgement signal has been reached by HMI: V1700 2001.0 or
V1700 2001.1 and evaluates this immediately. The acknowledgement signals are available
for one PLC cycle once they have been received and are then automatically deleted by the
PLC operating system.
