Supported device types and versions


The protocol ensures reading ID datasheet from RFID modules, ID series by ID-Innovations.

Communication line configuration


Line protocol parameters


Communication line - configuration dialog box - Protocol parameters tab.
They influence some optional protocol parameters. The following line protocol parameters may be set:

Table 1

Parameter Meaning Unit /size Default value
a name="MT">Moxa Redundancy Check Timeout A switching period of Moxa redundant equipment in case of longer communication pause. It is relevant only on SerialOverUDP Device Redundant line. sec 30 sec

Communication station configuration


  • Communication protocol "ID-Innovations RFID ASCII Protocol".
  • Any address parameters are not required. Only one ID-Innovations sensor may be connected to the line. Because of a random module sending only in the moment of card loading, some conflicts could occur on transmission line.

I/O tag configuration


Possible I/O tags: Ci, Co, TxtI.

These three I/O tags must be configured to work properly:

I/O tag Address Meaning
TxtI 1 This text input acquires the value of ID read from RFID card. ID of card is a hexadecimal number.
Ci 1 A cardinal input value incremented with every a new ID published in a text I/O tag.
Co 1 After the ID published in TxtI is processed, the same value, as is in Ci, must be written into this I/O tag. This handshaking ensures that no information about the received ID will be lost.
