Bit writes to C type variables are supported. The process of writing a single bit in a C variable is called
Read-Modify-Write, where the variable is read, the desired bit is changed and the whole byte is written
back to the PLC. If the contents of the C variable is changed by the PLC during the Read-Modify-Write
operation, the byte value will be the new value of the QUICKPANELï›› write operation.
V locations can be interpreted as Signed Integer, Unsigned Integer, or BCD. The normal interpretation
of a V location is Signed Integer. Reading V locations in a different format is done by adding a colon
and a suffix to the V location address.
V100:C Read or Write the contents of V100 as BCD 0000-9999
V100:I Read or Write the contents of V100 as Signed Integer -32767 to 32767
V100:U Read or Write the contents of V100 as an Unsigned Integer 0 to 65535
