the parameter data block (UDT 10).
Figure 2-4 Setting the physical address assignment in UDT 10
In addition to the address (ASM_address), the RFID channel (ASM_channel) must also be
assigned uniquely. If a communications module is operated with two channels, a separate
UDT 10 must be defined for each channel. The "ASM_address" entry is the same. The
"ASM_channel" is set from 1 to 2.
