SECS/GEM COMMUNICATION SOFTWARE
KNOWLEDGE
This section describes the points and knowledge to conveniently use SECS/GEM communication when using SECS/GEM
communication software.
9.1
Checking the Completion of Starting the SECS/
GEM Communication Software
Series
MELSEC-Q series
MELSEC iQ-R series
In the case of a ladder program of a programmable controller CPU, always first make sure that the [CIM Control READY] relay
that reports from the SECS/GEM communication software is ON after starting the SECS/GEM communication software.
When the start-up process of the SECS/GEM communication software finishes, the CIM Control READY relay switches ON.
A handshake with SECS/GEM communication software cannot be used until this relay switches on.
Usage method
To use notification of the CIM control ready relay, it is necessary to configure the relay to report. ( Page 99 CA status)
After the SECS/GEM communication software starts, first make sure that the CIM control ready relay is ON.
A handshake with SECS/GEM communication software cannot be used until the [CIM Control READY] notification relay turns
ON.
9.2

Checking the SECS Line State

Series
MELSEC-Q series
MELSEC iQ-R series
The connection state of the SECS communication line is reported by the Disconnected relay.
This relay turns OFF when the line is connected and turns ON when the line is disconnected.
In the case of HSMS communication, the TCP/IP communication line is established, the "select" control procedure is
completed via a HSMS message, and then a line connection is created by the Selected state.
In the case of SECS- communication, a line connection is created when the RS-232C line is completely opened.
Usage method
To use notification of the Disconnected relay, it is necessary to configure the relay to report. ( Page 99 CA status)
Precautions
The line connection state of the SECS communication line can be checked by the Disconnected relay.
In the case of HSMS communication, a line connection state is not formed by just a TCP/IP line connection.
