Displaying Data from Other Meters
Data can be read at a workstation using ION Enterprise software, but there may be
situations which require the data to be read at the source. With just one Power PC
meter, such as an ION 8500 or ION 7500, you can view the data collected by
numerous TRANs and other devices over a serial network. This is done using the
Modicon Modbus protocol. The ION meter with the front panel display acts as the
Modbus Master, and the other meters are the Modbus Slaves. Thus, the display
meter has its protocol set to

TRAN is short for “transducer.” A TRAN meter is a basic meter model without a front panel display; a
TRAN can be used with a remote display.

An ION 7500 / ION 7600 meter must be configured with the v2.2 or later firmware, and an ION 8000
Series meter must have v218 or later. These particular firmware versions provide the ION meter with
Modbus Master functionality.

Customized Display Framework
The ION 7500 with front panel display is the Modbus Master that is showing data

If this were the complete display framework, then there would be a total of four
screens showing data on the ION 7500 with front panel display: one screen from
each TRAN (the ION 7500 and the ION 7300) and two screens from the ION 6200.
Notice how the ION 6200 has had its data displayed on different screens.

Use the ReadNow input of the Modbus Import module if you want to setup a
trigger source that activates a read (i.e. a pulse). If you do not link ReadNow the
module polls Modbus devices continuously.
