    X is a space for positive value or “-” sign XWWWWW is the total value XYYYYY is the grand total value PM5-TMR <STX>XZZZZZZ<CR> where: X is a space for positive value or “-” sign ZZZZZZ is the time (up to 6 characters/spaces) decimal points and colons can additionally be displayed e.g.
  • Page 20 POII - Host Controlled Transmit Mode 10.2 This mode requires a host computer or PLC to poll the instrument to obtain display or other information or reset various setpoint parameters. Terminal communications software is required when using POLL mode with a PC. Data is in ASCII format with 8 data bits + 1 stop bit. Addresses are offset by 32 Dec.
  • Page 21 Model Primary display value PM5-CO Channel 1 value Display value in UAL, ASCII, in131 modes PM5-RS Wind speed in NMEA mode PM5-TR Rate value 2.
  • Page 22 PM5-C0 Temperature 1 value PM5-RS Not used PM5-TR Grand total value 4. Transmit Quad Display Value: <STX>QA<CR> e.g. BQ! M using a terminal program (address 1). Instructs unit to return the quad display value. If no quad display value is used the instrument will return an invalid command character “?”.
  • Page 23 If the address received from the host does not match the units address then the unit will not respond at all. Host Timing Requirements for RS485 Operation: RS485 operation requires the host to switch the RS485 transceiver to transmit before a command is sent.

  • Page 25: Analog Pi Control Output

    Analog PI control output PI control functions will only be seen if PI control software is available for the instrument and if the optional isolated analog or dual isolated analog output is fitted. The PI (proportional + integral) control output may be configured for proportional only (i.e. integral gain set to 0.000) or proportional + integral control.
  • Page 26 PROCESS Process above setpoint Process at setpoint SETPOINT Process below setpoint TIME To set the selection go to the function, press F and when you see a digit of the value flash use the ^ or v push buttons to set the required value then press F to accept this selection. 12.4 Analog output 1 PI control span SPAn...
  • Page 27 Example 2 - if the proportional gain is set to 2.000 and the measured input changes by 50% of the range set in then the output will change by 100%. Example 3 - if the proportional gain is set to 2.000 and the measured input changes by 25% of the range set in then the output will change by 50%.
  • Page 28 will be a 100% output (e.g. 20mA for a 4-20mA output) when the process reaches the setpoint value. If using proportional only control then when stable control is established there may be a difference between the process and the setpoint values. By altering the bias value the difference may be minimised.
  • Page 29 12.8 Analog output 1 PI control integral gain Display: -32.768 to 32.767 Range: Default Value: 0.000 Allows selection of the PI control integral gain. The integral control action will attempt to correct any offset which the proportional control action is unable to correct (e.g. errors due to a changing load).
  • Page 30 control will see a large error. Since integral control output increases with time, the longer an error is seen the more the integral control output will build up. Unless the output is limited then once the process reaches the setpoint the integral control output can be very large (e.g. 100%) causing the process value to overshoot the control setpoint.
  • Page 31 increase or decrease the proportional offset value until the displayed value matches the control setpoint value. If process load changes occur then the proportional offset value may no longer be valid for offset free control. By introducing the integral action, setpoint offset caused by the process load changes will be minimised.
