Commands
<Ident channel>=0 allows you to assign the trigger signal to channel '0' so that the trigger
signal is transmitted to the controller and not to a read head.
This function can be used to monitor functions via the PLC if trigger signals and reading of data
cannot occur simultaneously for application related reasons. Correlation must take place in the
PLC.
7.12 Standard read/write commands
Single read fixcode (SF)
Command:
Response:
The R/W head makes only one attempt to read a read only code.
The length of the read only code that is output depends on the tag type. See table "Supported
Tag Ty pe s " on p ag e 5 8 .

Table 7.13 * this byte is only used with the TCP/IP and MODBUS TCP/IP protocol.
1) The telegram length depends on length of the read only code from the tag.
2) N = <FixLen> + 6; Ethernet/IP: N = <FixLen> + 4
