Operating states of the
PLC The PLC can have the following operating states:
“Run”, “Ready”, “Not Ready”.
Ready
The “Ready” status means the following:
There is a user program loaded in the PLC;
The user program is not running;
The outputs are reset and disabled.
The PLC is switched to the “Ready” status:
If the “Reset” button is pressed when the
operating mode selector switch is set to “Halt”;
After the power supply is switched on if the
operating mode selector switch is set to “Halt”;
By means of the programming software on the
PC;
In slave mode, if the master switches to the “Halt”
(stop) status and you have set in the slave
parameters the “remote control” function to ON in
the Sucosoft Topology Configurator (see
AWB2700-1305GB, chapter 5);
If the tab of the memory module is pulled out.
Communication with the PC is possible in all
three operating states. Accordingly, the current
status of the PLC and the real-time clock can
always be read, for example.
