ConnecƟ ng to Remaining Controllers

Bridged communica on on the 485 network requires both physical and so ware connec ons be made with

each controller manually. The sequence in which these connec ons are made does play a role in ensuring

reliable communica on. Begin by removing all power from the bus and controllers. This is a cri cal step as

physically connec ng wire/cable to controllers during normal opera ons has been shown to result in commu-

nica on errors. Once power has been removed, connect all wire/cable to the controllers/adapters. Ensure TS-

MPPT-60 conﬁ gured to bridge communica ons had been connected to both the bus and LAN/WAN. Restore

power to all devices and observe proper LED indica ons (if equipped).

Once all equipment has been physically connected to the 485 bus, so ware(MS View) connec ons must be

established to allow for bridged communica ons. To begin, the user must ﬁ rst establish communica ons with

the Bridge Enabled Master/TS-MPPT-60. Once connected to the Master controller, the IP address may be

veriﬁ ed by viewing the Connec on tab within Device Proper es. Each subsequent device must be manually

added and connected to the network using the procedure listed below:

1: In MS View, select Devices => Manual Connec on.

2. Highlight the device to be connected and click OK. This will open Device Proper es page.

3. Change Connec on Type to “Remote (TCP)” on the Connec on Tab on the Device Proper es Page

4. Enter the IP address the TS-MPPT-60 conﬁ gured as the Modbus/IP Bridge

5. Enter the controller Modbus ID in the “Control Address” ﬁ eld and click OK

*the Controller should now be displayed in the MS View Device pane.

6. Right-click the controller and click Connect.

Note: The Morningstar Relay Driver has a default Modbus ID of 9.
