Parameter Description
Specifies the coil address with
dress 1 which the following bit coded
register value is accessible.
The register and bit(s) are
specified by Modbus coil reg‐
ister 1and Modbus coil bit‐
mask 1
Specifies the Modbus register
register 1 whose value is checked
against Modbus coil bitmask 1
to determine the coil value
(false or true). A register value
of 65535 specifies that this coil
mapping is undefined.
Bit mask which is compared
mask 1 against the register value
specified with Modbus coil reg‐
ister 1 to determine the coil
value. If any bit of the register
value is set which is also set
in the bit mask then the coil
value is true, otherwise the
coil is false.
Output parameter that informs
length 1 about the size in bytes of the
parameter that is specified by
Modbus coil address 1. Could
be used to identify the relevant
bits of the Modbus coil bit‐
mask 1
Specifies the coil address with
dress 2 which the following bit coded
register value is accessible.
The register and bit(s) are
specified by Modbus coil reg‐
ister 2 and Modbus coil bit‐
mask 2
Specifies the Modbus register
register 2 whose value is checked
against Modbus coil bitmask 2
to determine the coil value
(false or true). A register value
of 65535 specifies that this coil
mapping is undefined.
