Issue Number: 3
Parameter
S.01.005
is used to disable or enable relevant bits in the Output Register (Pr
S.01.007
).
If the bit is set to zero, the relevant bit in the Output Register (Pr
S.01.007
) is disabled. If the bit is set to 1 then the relevant bit in the Output Register
can be used to directly control the digital output but the conditions below will need to be fulfilled:
•
The corresponding bit in the I/O Output Enable Register (Pr
S.01.005
) is set to 1.
•
The I/O must be a digital I/O and configured as an output or is a Relay Output.
•
The corresponding I/O Source/Destination parameter must be set to 00.000.
If the above conditions are not met, then the digital output is controlled by the normal logic.
The table below shows how the bits correspond to each function.
The Digital I/O Input Register (Pr
S.01.006
) is always active and displays the state of all the digital I/O which are configured as inputs.
This register is updated every 1 ms.
The table below shows how the bits correspond to each function.
Bits in the I/O Output Register (Pr
S.01.007
) can be used to control the digital I/O directly. The bits control the output directly and are not modified by
the corresponding Digital I/O Invert function. The bits in the I/O Output Register (Pr
S.01.007
) only control the corresponding digital output if all the
conditions below are met:
•
The corresponding bit in the I/O Output Enable Register (Pr
S.01.005
) is set to 1.
•
The I/O must be a digital I/O and configured as an output or is a Relay Output.
•
The corresponding I/O Source/Destination parameter must be set to 00.000.
If the above conditions are not met, then the digital output is controlled by the normal logic.
The table below shows how the bits correspond to each function.
