Calibrate the mA output following the procedure in section 6.2
Display scaling values will be automatically shown correctly, but if AUTO is off, they can
be changed from the default 0-100% by following the procedure in section 6.3
The IWR-Port output is channel 1 parameter 1.
The parameter that it represents must be changed to channel 2 parameters 1 by following
the procedure described in section 6.5.
Measure the age of a reading in minutes by following the procedure in section 6.15.
Exit the main menu by holding both buttons until OK is displayed.
3.3 Example 3
The IWR-Port receives value from 4 IWmAT and outputs these as 4-20 mA outputs
using an Isoslice-8 analog output card as well as providing them as MODBUS RTU
values over an RS485 network.
The IWmAT transmitters are configured to be channels 1,2,3 and 4.
Refer to the IWmAT installation instructions for details.
The Isoslice-8 unit is configured as channel 5.
Refer to the Isoslice-8 installation instructions for details.
Fit the Isoslice-8 and IWR-Port units to the din rail.
Connect power and RS-485 cable to the IWR-Port then switch on (see section 4)
Access the main menu by pushing and holding both buttons until OK is displayed.
Display scaling values will be automatically shown correctly for the 4 IWmAT devices, but
if AUTO is off, they can be changed from the default 0-100% by following the procedure
in section 6.3.
The Isoslice-8 outputs must be configured to represent the 4 IWmAT values of channels
1,2,3 and 4 by following the procedure described in section 6.5.
Select the network protocol by following the procedure in section 6.9.
Set up the Modbus slave address by the following procedure in section 6.10.
Set up Serial port options by following procedures in sections 6.11,6.12 and 6.13.
Measure the age of a reading in minutes by following the procedure in section 6.15.
Exit the main menu by holding both buttons until OK is displayed.
Calculate the registers to read by referring to section 9.1.
