Parameter Description
Bit mask which is compared
mask 2 against the register value
specified with Modbus coil reg‐
ister 2 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 false.
Output parameter that in‐
length 2 forms about size in bytes of pa‐
rameter that is specified by
Modbus coil address 2. Could
be used to identify the rele‐
vant bits of the Modbus coil
bitmask 2
Output parameter that in‐
length 20 forms about the size in bytes of
the parameter that is specified
by Modbus coil address 20.
Could be used to identify the
relevant bits of the Modbus
coil bitmask 20
