AH 5 00 Pr ogr am m ing Ma n ua l

Explanation:

Users can use this instruction to write the data in the AH500 series PLC into the control

The operand m

should be within the range between 1 and 8. 1 represents a main rack, and

2~8 represent extension racks.

The operand m

should be within the range between 0 and 11. If the rack code is 1, the slot

code should be within the range between 0 and 11. If the rack code is within the range

between 2 and 8, the slot code should be within the range between 0 and 7.

The operand m

specifies the control register number.

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.

The operand n used in the 16-bit instruction should be within the range between 1 and 256,

and the operand n used in the 32-bit instruction should be within the range between 1 and 128.

Only the 32-bit instructions can use the 32-bit counter.

Special modules include analog I/O modules, network I/O modules, and position I/O modules.

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.
