CHAPTER 10
SLMP is a protocol that enables connected devices to access SLMP supporting devices over Ethernet.
SLMP communications are available among devices that can receive/send messages in the SLMP control procedure.
This function is available only in the QJ71E71-100 with the serial number (first five digits) of "15042" or later.

Applications

Applications of SLMP communications are as follows.
(1) Data read/write
Data can be read/written from/to a device of the CPU module where an E71 is mounted and intelligent function
module buffer memory. This allows a connected device to monitor the operation of the CPU module where an
E71 is mounted, perform data analysis, and manage production control.
(2) Remote control of a CPU module
The remote operation allows a connected device to remotely operate a CPU module where an E71 is mounted.
(3) Turning off the COM.ERR. LED
The COM.ERR. LED on an E71 can be turned off from a connected device.
