BACK DISPLAY
The back display, which has two lines with 16 characters each, always shows the I/O status.
It serves mainly for the case of the PLC300 mounted without HMI (keyboard and front
display). If there is a front display, it helps check the status from the inside of the panel door.
The initial screen shows the status of the internal digital I/Os, that is, DI10 to DI01 and
DO09 to DO01.
By pressing the back key, we alternate the status screens. Those screens depend on
the hardware, for instance, whether there is expansion or not, and the DO9 digital output
function.
Internal digital inputs and outputs
The level of the ten internal digital inputs can be checked on the first screen: DI10 to DI1
and of the internal digital outputs.
I 1 0 - 1 : 0 0 1 0 0 0 1 0 1 1
O 0 9 - 1 : 1 0 0 0 1 1 0 0 0
In the example, the outputs 1, 2, 4 and 8, as well as the outputs 4, 5 and 9 are active.
If the digital output 9 is programmed as PWM rapid output, instead of 0 or 1, the letter
‘P’ is shown.
I 1 0 - 1 : 0 0 1 0 0 0 1 0 1 1
