−Limitations−
• No. of AN712 modules: 4 per station: Model 3000 only
• No. of sockets per AN712: 12
• Protocol: Commands of only UDP/IP usable
• Transmitting text size: 500 words
−Functions−
• ADMAP-5M message transmission by the UDP/IP communication function
• When the execution request (REQ) changes from FALSE (OFF) to TRUE (ON), (N)
words of receiving data (P) are transferred depending on the specified request
command (CMD).
• Up to 500 words of receiving data can be specified.
• When data reception is completed, the done output (DONE) becomes TRUE (ON) for
1-scan time only.
• If data reception ends in an error, error (ERROR) becomes TRUE (ON) for 1-scan time
only.
• When data reception is completed or ended in an error, its detail is output to status
(STATUS).
• The instruction is completed normally (DONE=ON) at the second or later scan after
execution is requested (REQ=ON). Remember that, depending on the set control
cycle and the way of creating an application program, it may take a few seconds for
the normal completion of the instruction.
