10.3 Data Communication Procedure
The following is a data communication procedure for SLMP communications.
1. Set the parameters. ( Page 92, Section 10.4)
2. Perform the open process and establish a connection between the E71 and the connected device.
( Page 72, Section 7.2, Page 79, Section 7.3)
3. Once the connection is established, the connected device sends an SLMP message.
4. The connection is closed after the communications are completed.
In the cases described below, an E71 performs a remote password check when the connected device accesses the
programmable controller. If communications cannot be performed, unlock the remote password. ( Page 182, Section
14.4.2)
• When a remote password has been set in the CPU module
• When the connection for data communications with the connected device is to be subjected to the remote
password check
