In order to avoid communications issues:
Baud rate, protocol and data format settings need to be the same for all the
connected serial devices.
Each serial device must have a unique Unit ID.
The gateway device must have the same baud rate and data format settings as
the connected serial devices, if these can be configured.
EGX series considerations
The PowerLogic™ EGX series Ethernet gateway can provide Ethernet access to
multiple RS-485 devices that are connected to the EGX’s RS-485 port. After wiring
the RS-485 devices to the EGX, use a web browser to log in to the EGX. Browse
to the device list page and enter each device that is connected to the EGX’s
RS-485 port. Set the appropriate device address and device type for each device.
Refer to the EGX Series Installation Guide.
After you add the devices to the EGX’s web page, you must add an Ethernet
gateway site to ION Setup and then add those devices to the gateway site. See
“Adding and Configuring Devices” on page 41 for more information.
PM8ECC considerations
Similar to the EGX series gateway, the PM8ECC Ethernet communications card
provides Ethernet access to multiple RS-485 devices that are connected to the
PM8ECC’s RS-485 port. After wiring the RS-485 devices to the PM8ECC, use a
web browser to log in to the PM8ECC. Browse to the device list page and enter
each device that is connected to the PM8ECC’s RS-485 port. Set the appropriate
device address and device type for each device. Refer to the PM8ECC Installation
Guide.
After you add the devices to the web page, you must add an Ethernet gateway site
to ION Setup and then add those devices to the gateway site. See “Adding and
Configuring Devices” on page 41 for more information.
ION meter EtherGate considerations
When an Ethernet-capable ION meter has EtherGate enabled, a workstation using
ION Setup software can communicate through the meter to a serial device (or
devices) wired to the appropriate serial communications port of the EtherGate-
enabled meter.
When you configure the EtherGate-enabled meter (in addition to the general
settings listed above), the protocol for the serial communications port must be set
to EtherGate
For more information on using your meter as an EtherGate, refer to the gateway
meter’s documentation and the technical note The ION Meter as an Ethernet
Gateway.
To connect to and read data from your EtherGate meter, in addition to the serial devices, add it as a
stand-alone Ethernet meter in ION Setup. See “Adding a New Meter” on page 53.
