measurements
Shows when the controller is added to the Telegram menu. For each measurement tag
(1 to 16) added in the Telegram menu, select a Parameter and Unit that will show on
the tag for external measurements as follows:
1.
Select Parameter and Unit.
2.
Select Search parameter and search for related parameters. For example, enter
DO to find all of the parameters related to dissolved oxygen. A message shows the
quantity of parameters found. Push OK.
3.
Select Parameter to go to the list of parameters found.
4.
Select one parameter, then push OK.
5.
Select Unit to select one unit based on the selected parameter.
6.
Apply changes to save the configuration.
7.
Do the steps again for the other text parameters or go back to the Modbus TCP
menu.
4.
Push OK.
6.5.5 Configure the Profibus DP
Use Profibus DP (Decentralised Peripherals) to operate sensors and actuators with a centralised
controller in production (factory) automation. Make sure that a digital Fieldbus module is installed in
the controller. Refer to the documentation supplied with the module. Make sure that all of the
necessary electrical connections are complete before the settings are configured.
Configure the Profibus DP settings as follows:
1.
Push the main menu icon, then select Outputs > Profibus DP.
2.
Set the Profibus DP button to on.
3.
Select an option.

Description
Profibus DP
Selects one of the options that follow:
• Fieldbus address—Changes the slave address.
• Data order—Sets the byte sequence for the transmission of floating point values. A
floating point value has 4 bytes. Options: Normal—IEEE Float Big Endian (default). The
pairs are not changed. The Normal Data order mode can be used with all known
Profibus master systems. Swapped—IEEE Float word wise swapped. Changes the first
byte pair with the last byte pair.
Telegram
Manages the Telegram data structure. Select the devices and the device data tags in the
Telegram. Refer to
on page 38.
Simulation
Simulates two floating point values and errors (or statuses) to replace an instrument. The
first floating point value goes through a ramp between limits set in the Minimum and
Maximum menus.
• Simulation—Enables or disables the simulation.
• Period—Sets the time in minutes (0 to 65535) for the first floating point value to go
through the full range between Minimum and Maximum settings.
• Maximum—The upper limit for the first floating point value. Range: –3.402823E to
3.38
• Minimum—The lower limit for the first floating point value. Range: –3.402823E to
3.38
• Error—Sets the value in the first simulated register. Range: 0 to 65535
• Status—Sets the value in the second simulated register, Range: 0 to 65535
• Toggle—Changes the direction of the simulated ramp application.
Version
Shows the software version of the Profibus network module.
