The following example illustrates how the states of multiple coils are changed by using function code 0F
hex. In this example, 400 bits of data starting from register OB120000 in the local station are written to
registers starting at MB00010000 in the remote station.
1. If the coil offset parameters in the MSG-RCVE function are set to a non-zero value, the actual
addresses that are written to in the remote station will be the sum of the remote station data
addresses and the word offset value in the coil offset parameters.
2. Set the address of the registers to write to within the range specified by the M Register Writing
Range Low and M Register Writing Range High parameters in the MSG-RCVE function. Data will
not be written if an address exceeds the valid setting range.
