3.5 Force Single Coil (05)

This function is used for forcing the status of a single binary variable ON

or OFF. Broadcast mode is allowed.

Question

In addition to the address of the slave and the function code (05), the

message contains the address of the variable to be forced in two bytes

and two characters of which the first is set to FFh (255) to force it ON and

00h to force it OFF, while the second is always set to zero. Address

numbering starts from zero (bit1 = 0) for MODBUS, from one (bit1 = 1) for

JBUS.

Example: Request to force bit 4 on slave 47 ON.

the address of the variable expressed in two bytes and the value to be

assigned. Address numbering starts from zero (word1 = 0) for MODBUS,

from one (word1 = 1) for JBUS.

Example: Request to force address 26 of slave 38 to 926.
