3.2 Reply Format
Every time a command has been sent to a module, the module sends a reply.
The reply format with RS-232, RS-485, RS-422 and USB is as follows:
TMCL Reply Format
Bytes Meaning
1 Reply address
1 Module address
1 Status (e.g. 100 means no error)
1 Command number
4 Value (MSB first!)
1 Checksum
Table 2: TMCL Reply Format
Info
The checksum is also calculated by adding up all the other bytes using an 8-bit
addition. Do not send the next command before having received the reply!
Note
When using CAN interface, the reply does not contain an address byte and a
checksum byte. With CAN, the CAN-ID is used as the reply address and the
checksum is not needed because the CAN bus uses hardware CRC checking.
3.2.1 Status Codes
The reply contains a status code. The status code can have one of the following values:
