If there is no program on the base device, the base device will remain in the
STOP operating mode and it will not be possible to execute any programs.
l
If a program has been loaded onto the device, the base device will remain in the
STOP operating mode until it switches to RUN. When the base device is in STOP
mode, the program will not be executed. Connected expansion devices will com-
municate with the base device as long as there are no configuration errors, and
all the outputs on all devices will have a state of 0 (OFF). In addition, it will be pos-
sible to communicate with easySoft 8 via Ethernet.
l
The base device can be switched to the RUN operating mode with the menu or
through easySoft 8. In this case, the program will be executed and the outputs
will be switched on and off as per the program logic. Existing communication ser-
vices such as NET, Modbus, web servers, etc. will be running, and it will be pos-
sible to use them.
