(e.g. G401190)

INT / REAL / LONG / BCD / LONGBCD / STRING

Individual Extended Register

G<EF:R>

where:

E denotes the extended register.

F is the file number between 1 and 16 inclusive

R is the register between 0 and 9999 inclusive

INT/ REAL / LONG / BCD / LONGBCD / STRING

Note: When writing DIGITAL variables to output registers, the individual bits in a register (1..16) can be written to with the format n.BitPosition (e.g. 40001.1). Writing to sequential bits requires individual write commands. The user can specify the bit order direction in the INI parameter [MODNET]RegisterBitReverse.
