Explanation:
1. Users can use this instruction to write data in an AH500 series PLC into a control register in a
network module.
2. The operand m should be in the range of 1 to 8. 1 represents a main rack, and 2~8 represent
1
extension racks.
3. The operand m should be in the range of 0 to 11. If the rack code is 1, the slot code should be
2
in the range of 0 to 11. If the rack code is in the range of 2 to 8, the slot code should be in the
range of 0 to 7.
4. The operand m specifies the control register number.

5. When the instruction TO is executed, D is set to 0. When an error occurs, D is not set to 0.
Please refer to the additional remark below for more information about the error codes.
6. The operand n used in the 16-bit instruction should be in the range of 1 to 256, and the
operand n used in the 32-bit instruction should be in the range of 1 to 128.
7. Only the 32-bit instructions can use the 32-bit counter.
8. When S is a decimal value or a hexadecimal value, n decimal values or n hexadecimal values
are transmitted to the I/O module. Suppose S is 16#0001 and n is 3. Three 16#0001s are
transmitted to the I/O module.
