4.1 System Configuration

SLMP COMMUNICATION
Since the LE7-40GU supports the SLMP communication function which is an open FA network, it can communicate with
various SLMP-compatible devices. Also, up to seven LE7-40GU units can be connected to one SLMP-compatible device to
carry out data monitoring and parameter writing.
Precautions
If you replace an external device or an SLMP equipment due to a malfunction, the MAC address of the connected device
changes, so communication may not be possible. (When exchanged with the same IP address equipment)
If you replace a device in the Ethernet, restart all the devices in the network.
4.1
System Configuration
*1 Please connect with SLMP equipment via a hub.
Use cables, connectors, and hubs that satisfy the IEEE 802.3 10BASE-T/100BASE-TX/1000BASE-T standard.
*2 When connecting LE7-40GU to 10 BASE (- T/2/5) compliant equipment, use it in a network environment where 10 Mbps/100 Mbps can
be mixed using a switching hub.
*3 This is the length between the hub and the node.
The maximum distance depends on the Ethernet device used.
When using a repeater hub, the number of units that can be connected is as follows.
· 10BASE-T: Cascade connection up to 4 units (500 m)
· 100BASE-TX: Cascade connection up to 2 units (205 m)
When using a switching hub, the cascade connection between switching hubs has no theoretical limit on the number that can be
cascaded.
Please check with the manufacturer of the switching hub used for any restrictions.
*4 For the twisted pair cable, please use a straight cable.
*5 For details, refer to the manual of the SLMP equipment used.
