• Multipliers to change data to/from integer. 10, 100, 1000, 256 ... The Modbus RS-485 interface discussed in this manual is an option for Sierra’s InnovaMass 240i and 241i Vortex Volumetric Flow and Multivariable Mass Flow. The interface makes it possible to connect the InnovaMass to a Modbus network and remotely operate it. -
Page 7: Electrical Connections
Electrical Connections All electrical connections are made on the terminal board inside the InnovaMass enclosure. Instrument Power Connection DC Power - DC Power + Power supply requirements for the InnovaMass are the following: Voltage: 24 VDC +/- 10%, Amperage: 1.1 A Modbus RS-485 Connection Caution! The InnovaMass is equipped with an optical isolated RS-485 interface. -

Modbus data. In addition, it also provides for safety, EMI, RFI, and ESD protection. Both the main and remote (if E4 option ordered) enclosures should be connected to earth ground, see below for more details. A. External Earthing: The external earthing connections are located on the boss on the outside of both the main housing and remote housing (E4 option if ordered) and consist of an 18-8SS pan head Phillips screw (10-24 UNC-2B thread) and a serrated tooth #10 ring terminal for 16-14 AWG wire. -
Page 10: Cable
Cable It is recommended to use shielded twisted pair type of cable (reduces radiated and received EMI). Use a 24 AWG shielded twisted pair cable, with low capacitance like Belden 9841. Terminator Reflections in a transmission line can cause communication errors. To minimize the reflection it is required to place 120Ω... -

Caution! Exceeding the numbers of suggested registers will raise an exception code. Registers Explained The registers are divided into two groups. The first group (40001 – 40009) represents the dynamic data that changes the most of the two groups. The second group (40010 – 40131) contains the settings in the flow meter. - Page 15 0 - SCFS 23 - NCFD 51 - NLPM 109 - Lton/yr 1 - SCFM 24 - NCFY 52 - NLPH 110 - Mton/sec 2 - SCFH 25 - SM3/sec 53 - NLPD 111 - Mton/min 3 - SCFD 26 - SM3/min 54 - NLPY 112 - Mton/hr 4 - SCFY...
