DigitalInputs
Root/Objects/DeviceSet/Read_point_x/IOData/DigitalIOPorts/Digi
talInputs
String
R
Supplies the states of the digital inputs of the communications
module.
0000 ... 1111
Binary characters (0, 1) per input
Each position stands for an input of the communications module:
•
•
•
•
Depending on the value of the particular position, the corre-
sponding input is at "ON" (1) or "OFF" (0).
DigitalOutputs
Root/Objects/DeviceSet/Read_point_x/IOData/DigitalIOPorts/Digi
talOutputs
String
R/W
Supplies the states of the digital outputs of the communications
module and allows the states of the output to be set.
0000 ... 1111
Binary characters (0, 1) per output, also "x" on setting for mask-
ing out
Each position stands for an output of the communications mod-
ule:
•
•
•
•
Read: Depending on the value of the particular position, the
corresponding output is at "ON" (1) or "OFF" (0).
Write: Depending on the value of the particular position, the cor-
responding output is set to "ON" (1) or "OFF" (0). Outputs whose
state is to remain unchanged can be masked out with "x".
Example:
xx01
Outport03 and Outport02 remain unchanged, Outport01 is
switched off, Outport00 is switched on.
Inport00: 1st position (least significant bit right)
Inport01: 2nd position
Inport02: 3rd position
Inport03: 4th position
Outport00: 1st position (least significant bit right)
Outport01: 2nd position
Outport02: 3rd position
Outport03: 4th position
