(5) ACT1 LED [ACT]
When the LINK1 LED is on, this LED flashes when the module is communicating with the expansion interface remote master
module or upstream expansion interface remote slave module.
(6) LINK2 LED [LNK]
This LED turns on when the downstream expansion interface remote slave module is connected to expansion port 2 [Exp.
port S2] using an Ethernet cable.
(7) ACT2 LED [ACT]
When the LINK2 LED is on, this LED flashes when the module is communicating with the downstream expansion interface
remote slave module.
(8) Expansion Connector
This connector is used to connect an expansion module.
(9) Expansion Port 1 [Exp. port S1]
This port is used to connect the expansion interface remote master module or upstream expansion interface remote slave
module to the module using an Ethernet cable.
(10) Expansion Port 2 [Exp. port S2]
This port is used to connect the downstream expansion interface remote slave module to the module using an Ethernet cable.
(11) Power Supply Terminals
These terminals supply 24V DC power to the expansion interface remote slave module.
(12) Expansion Port 2 [Exp. port S2] Cover
A removable cover that protects expansion port 2 [Exp. port S2]. When using expansion port 2 [Exp. port S2], remove the
expansion port 2 [Exp. port S2] cover.
