Operating status switch
Do not press the button if there is a potentially explosive atmosphere.
The switch is a combined element with switch and button functions. It has three settings:
●
RUN mode
This is the basic setting for productive operation.
●
STOP mode
Set the TIM to STOP before disconnecting the power supply. Setting to STO may also be
necessary if an error/fault occurs to be able to restart the TIM afterwards.
In STO mode, the following functions are disabled:
– Telecontrol operation of the TIM
– Time-of-day synchronization via Telecontrol connections
– S7 connections are terminated.
The following functions remain enabled:
– Access to the WBM of the TIM
– Time-of-day synchronization with NTP
– Diagnostic functions of the TIM
