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 regis‐
ter 1and Modbus coil bitmask
1
Specifies the Modbus register
ister 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 in‐
length 1 forms 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 bitmask 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 regis‐
ter 2 and Modbus coil bitmask
2
Specifies the Modbus register
ister 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.
