11 Command that this is a response to. If an error has been detected, the command value will have the high bit set (OR with 0x80). For example: The Command is 0x10, so the command field in the response would be 0x90.

1	1	Error code, see Error Codes on page 164.

Example 1: Turn on the first relay on a D2R2 unit.

The first relay (R1) is a digital out coil register with a decimal value of 6659 (hex 0x1A03). Request: 0x0F 0x1A 0x03 0x00 0x01 0x01 0x01

Response: 0x0F 0x1A 0x03 0x00 0x01

Example 2: Turn on the first and second relay on a D2R2 unit.

The first relay (R1) is a digital out coil register with a decimal value of 6659 (hex 0x1A03). Request: 0x0F 0x1A 0x03 0x00 0x02 0x01 0x03 (03 = “00000011” which sets R1 and R2 to 1) Response: 0x0F 0x1A 0x03 0x00 0x02

Note: When reading or writing consecutive “Boolean” (coils) registers, the values of the registers are combined into a single byte as shown by the example above. Two registers (coils) are being written but the length of the data is 1 byte. The one byte contains the value for both registers as follows:
