14.1 DC PowerDC power is connected to pins 7 and 8 of the CMS circular connector(Red and Blue if using the pre-wired cable). All the other signalsare optional.Item Minimum MaximumVoltage 9V DC 36V DCCurrent200mA14.2 Serial InterfaceAn RS485 interface can optionally be connected to pins 1 and 3 (yellowand green). This can be a PLC running customer software, ora PC with a RS485 adaptor running the supplied CMS-View software.To provide a reference the RS485 0V connection should alsobe linked to the CMS 0V (as shown on the drawing).The standard CMS control protocol is Modbus RTU. Modbus is afreely available open standard for industrial control. Adapters areavailable to interface to other industrial control buses. The standardCMS-View software from RMF Systems itself uses Modbus tocommunicate with the CMS, but it is also possible for customers toimplement their own controllers – see chapter 18.44 Electrical Interface
Figure 14.2PC Control ExampleFigure 14.2 shows a single CMS linked to a PC, using a USB-RS485adaptor. 100 Ohm termination resistors should be fitted as shown forlong cables, for example over 10m. Twisted pair wiring should beused for any length over 2m.Contamination MonitorsFigure 14.3Multi-Drop Network ExampleFigure 14.3 shows how to connect two or more CMS devices to amulti-drop RS485 network. Any termination resistors should be fittedto the network cable ends only. Spurs off the main RS485 busshould be kept as short as possible, e.g. below 2m. Normally thepre-wired 3m cable available for the CMS would be used, with ajunction box to connect to the RS485 trunk. Either individual DCElectrical Interface 45
