Service Object Status
If it is desired to reflect the status of this service object, check the Reflect Status
checkbox and enter a database address between 0 and 4080 (0x0 – 0xFF0) at
which to store the status information. For more information on reflecting the
status of service objects, refer to section 8.4.2.
8.6.9.3 Configuration Example
This example will configure the gateway for end-to-end communication using
Metasys N2 master and Modbus RTU slave.
Say, for instance, we wish to communicate to an adjustable-speed drive that
supports Metasys N2 from a PLC that supports Modbus RTU. We wish to monitor
the output frequency, output current, and output voltage of the drive, located at
analog input objects 1, 2 and 3, with multipliers of 0.01, 0.01, and 0.1
respectively. We'd also like to monitor the running, forward/stop, and reverse/stop
bits, located at binary input objects 1, 2 and 3, respectively. To run the drive, we
need to be able to command the frequency command at analog output object 2
with a multiplier of 0.01, the command forward/stop bit at binary output object 2,
and command reverse/stop bit at binary output object 3.
Configure the "RS-485 A" port (Modbus slave) using the above requirements
• Connect the gateway to the PC via a USB mini type-B cable.
• Open the configuration utility and select the XLTR-1000 (see section 8.1 for
more information on selecting a device).
• Click on the RS-485 A Configuration tab.
• Select Modbus RTU Slave from the protocol dropdown menu.
• Enter the Baud Rate and Parity settings to match that of the PLC.
• Enter the slave address that your PLC is configured to communicate with
into the Address field.
• The default mapping of the gateway's database into the Modbus register
space will be used, so no register remap objects need to be created.
Configure the "RS-485 B" port (Metasys Master) using the above requirements
Click on the RS-485 B Configuration tab.
•
Select Metasys N2 Master from the protocol dropdown menu.
•
• Create Service Objects to read and write the desired N2 objects:
o
We can create one service object to monitor the output frequency
and output current since they are the same type and have the same
multiplier value.
Select Analog Input from the Type selection group.
•
• Enter the address of the drive into the Dest Address field.
• Enter "1" into the Start Inst field.
• Enter "2" into the Num Insts field.
• Enter "0" into the Database Addr field.
• Select 32-bit Unsigned from the Data Type dropdown
menu.
• Enter "0.01" into the Multiplier field.
