The total response size given in this example equals 46 bytes.

The response contains the following four objects:

•Object no. 1: Manufacturer name (always "Télémécanique", i.e., 13 bytes).

•Object no. 2: Device catalog number (ASCII string; for example: “ATV212H075M3X”, i.e., 13 bytes).

The length of this object varies according to drive type. Use the “Length of object no. 2” field to determine the length.

•Object no. 3: Control version, in "MMmm" format where "MM" represents the major revision and "mm" the minor revision (4-byte ASCII string; for example: "0182" for version 1.82).

Error response:

Slave no.	Function code	Exception code		CRC16
Slave no.	Function code	Exception code	Lo		Hi
	AB
