Communications Control Protocol
The communications control procedure conforms to OMRON's SYSWAY protocol.
(1) The first right to send is held by the host device, and it is transferred to the ID Controller after a
command is sent.
(2) When a response is returned from the ID Controller, the right to send is transferred back to the host
device.
(3) The right to send is transferred by using a carriage return (CR).
(4) This protocol supports both 1:1 protocol and 1:N protocol.
(5) The 1:N protocol features one host device connected to more than one ID Controller (32 maximum).
A Controller number is added to the end of each command and response to identify the ID Controllers.
FCS (Frame Check Sequence) and horizontal parity are used to provide strict error detection.
(6) The 1:1 protocol features one host device connected to one ID Controller. To simplify the protocol,
horizontal parity is not used.
(7) The 1:N protocol can be specified even with a 1:1 connection (i.e., N = 1) to add a horizontal parity
check.
 Explanation
1. The host device sends a command to the ID
Controller.
2. The ID Controller analyzes the command from
the host device, transmits the command, and
writes data to or reads data from the memory in
the Tag.
3. For read commands, the read data and
response are sent to the host device. For write
commands, a response indicating that
processing is completed is sent to the host
device.
