1–6 Terminology Following are definitions of some of the terms used in this document. POWER LEADER – The GE family of comprehensive power management devices and system software used to minimize downtime and overall power cost. PMCS – Power Management Control System software.
Chapter 2 – Installation 2–1 Mounting The Ethernet Gateway may be mounted on a horizontal surface or on a wall, preferably inside an enclosure or switchgear lineup. The Gateway should be mounted so that it is spaced from enclosure walls or from other components in the enclosure.
POWER LEADER™ Ethernet Gateway Chapter 2 – Installation 2–4 Modbus Connection The Modbus RTU networks should be connected to the RS485 ports on the back of the Ethernet Gateway, as shown in Figure 9. Figure 9. Connecting an RS485 network to the Ethernet Gateway.
Modbus device, the Modbus Concentrator. Commnet is a communications protocol utilized by many of the devices from GE’s POWER LEADER family of power management devices. The Modbus Concentrator is a Modbus RTU device that permits commnet devices to be assigned Modbus-equivalent addresses.
POWER LEADER™ Ethernet Gateway Chapter 3 – Configuration Chapter 3 – Configuration The Ethernet Gateway needs to be properly configured to communicate with your RS485 networks. Two items are critical to proper performance of your Gateway: the Gateway’s Ethernet address communication settings.
NOTE: The lower portion of the Configuration Menu is labeled Advanced Options. These options are for use ONLY by GE technical support personnel. Do NOT select any of these options. IF YOU ACCIDENTALLY SELECT ADVANCED OPTION CONFIGURATION MENU, PRESS TO EXIT, THEN PRESS ...
3–6 Gateway Diagnostics Selecting menu item 11 exits the Gateway software and runs the Gateway diagnostics program. The Gateway Diagnostics menu shown in Figure 14 is displayed on the terminal. Figure 14. Gateway Diagnostics menu. Display Socket, IP Address and Subnet Mask Select menu item 1 to display the IP address and subnet mask for the Gateway.
Chapter 3 – Configuration Network Test – FACTORY USE ONLY NOTE: A client program may be requested from GE to run on the host when performing the network test. The client attempts to establish a connection to a server (the Gateway) with the specified IP address, subnet mask and port number.
POWER LEADER™ Ethernet Gateway Chapter 4 – Operation Chapter 4 – Operation The Ethernet Gateway, once properly configured, requires no user intervention for operation. During normal operation, the Ethernet Gateway passes messages to and from the attached Modbus devices and translates these messages between the Ethernet and Modbus RTU protocols.
POWER LEADER™ Ethernet Gateway Chapter 5 – Errors and Diagnostic Messages Chapter 5 – Diagnostic Messages and Errors 5–1 Monitor Mode The Ethernet Gateway can be set to send diagnostic messages to the RS232 port to be displayed on a terminal (see Chapter...
