5 2. LonWork 1. Need rebind if additional units (either annunciators or LonWork cards) are added GEZC ATS Controller Slide 5 of 23

6 3. Modbus (for MX150/250) If MX200/150/250 firmware version is 5.4 or below use Modbus 1.96 See O&M manual, 50R-2200 Regs up to 48 Card Assy P/N: 50P-1105 Configuration Assy P/N: 50P-1124 If MX150/250 firmware version is 6.0 or above use Modbus 2.1 See O&M manual, 71R-2200 Regs up to 232 Card Assy P/N: 50P-2035 Configuration Assy P/N: 50P-1124 Slide 6 of 23

7 4. Modbus Factory Configuration Connection differences between Modbus and MX150/250 Factory Configuration For MX150/250 factory configuration: 1. Connect TD(A) of 50W-1208 to Pin 2 (socket J4) of MX150/250 Controller via PS Connect TD(B) of 50W-1208 to Pin 1 (socket J4) of MX150/250 Controller via PS5133. For Modbus configuration/communication: 1. Connect TD(A) of 50W-1208 to the upper position via PS Connect TD(B) of 50W-1208 to the lower position via PS5140. RS232-to-485 Converter: 50W-1208 Belden Shielded Twisted Pair cable: Slide 7 of 23

8 4. Modbus Factory Configuration Modbus Factory Configuration Software (50P-1111) Rev 1.8 Belden Twisted Pair cable RS232-to-485 Converter: 50W-1208 Supporting accessory: One Port USB-232 converter (with GEZC s part number: 50W-1223 or NI part number: ) shall be used. For information about the USB converter, visit -- Slide 8 of 23

14 6. ModScan Software Step 1: Open browser to modscan folder Step 2: Double click ModScan32.exe Step 3: Click OK without enter info. Step 4: Wait till OK appears. Then click OK again. Need to know register map ModScan trial version have limited com time Slide 14 of 23

15 6. ModScan Software Need to know register map ModScan trial version have limited com time Slide 15 of 23

16 7. EnerVista ViewPoint GEZC P/N: EnerVista O&M manual: Trial Version can be downloaded at: Slide 16 of 23

17 7. EnerVista ViewPoint Step 1: Create a device name and intended COM settings (depends on the dominant equipment). Step 2: From the field Device Type, select OTHERS. Step 3: From the field Order Code, enter MX150 or MX250. Step 4: From the field Version, select 5.4x or 6.0x. Slide 17 of 23

21 10. Troubleshooting Technique of Troubleshooting Make sure Network option is ON For MX150/ can be set in user menu For MX200 Must be set in factory mode Slide 21 of 23

22 10. Troubleshooting Technique of Troubleshooting Make sure cable is less than 3000ft Otherwise add repeater. Perform local communication 1 master to 1 slave device Perform global communication a. Configuration via 50P-1111 b. EnerVista: b.1 Setup b.2 Plug-n-play Have spare (good) devices (I.e. Converter, Modbus card) Slide 22 of 23

23 11. Q&A Terminating Resistor For noise cancellation Noise issue due to EMI effect (I.e. Motor drive) Typically chassis ground one (master) end of shield but not both. (use Belden shielded pair) Network length up to 3000 feet More than 3000 feet will need a repeater Need to understand the register map Modbus connection is polarity specific LonWork s connection is non-polarity specific Conversion of Half-to-full duplex or vice versa: Use 50W-1225 Slide 23 of 23
