10.2.5.2 MODBUS protocol
If the device is not present on the network, check the following:
•
Make sure the AFA4000 is either in Run mode or is displaying the Diagnostics screen. The
comms are interrupted when the AFA4000 is in the pushbutton menus.
•
Power cycle the AFA4000. This is required if the protocol has been changed.
•
Make sure the network is MODBUS RTU.
•
Use the Diagnostics Menu to check the comms settings are correct (see below):
•
Tx & Rx = 0
AFA4000 is not connected to the network (initial
set up).
•
Tx & Rx >0 but fixed values
AFA4000 has lost connection to the network.
•
Rx is counting but Tx is a fixed
value
AFA4000 is connected to the network but the
Master (BMS) is offline or not polling the
AFA4000.
10.3 Config Manager
The TEL software package, Config Manager is used for uploading and downloading parameter
configuration files to the AFA4000. The Config Manager software is Windows based and requires
a RS232/485 converter and TEL comms adaptor to communicate with the RS485 comms port on
the AFA4000.
The software is free to download, and the comms adaptor is available to buy from TEL.
Most 3rd party RS232/485 converters will work with the AFA4000, the recommended converter
has the part number: - EasySYNC ES-U-2101-M.
The part number is also available to buy directly from TEL.
Recommended minimum PC requirements: -
•
Windows XP or later
