4.1 Protocols
2. Example:
DISOMAT with address 01 is to be tared remote-controlled via EDP.
Master (EDP)
<ENQ>
<STX>01#TG#<ETX><BCC>
2)
Taring is possible only under certain conditions, e.g. DISOMAT must have
recognized no-motion.
This may take some seconds. Therefore, DISOMAT sends an immediate
response message informing EDP that the command is being processed.
Master (EDP)
<ACK>
<ACK>
S=0: Command execution OK
S¹ 0: Command execution faulty
3)
DISOMAT tries to tare scale and, once command is successfully executed, sends
a response message including the information 01#AT#0# (user data).
If the command could not be performed (DISOMAT has not recognized
no-motion after a certain timeout), the response includes a number unequal to
0, e.g. 01#AT#1#.
Master (EDP)
<ACK>
<ACK>
