  MGate 4101-MB-PBS Configuration IO Mapping Setup In this page, you should define all commands that Modbus uses and all I/O modules PROFIBUS slave provides. If you choose MGate 4101-MB-PBS as Modbus Master, you should designate all Modbus Read or Write requests in the upper table.

• Page 28: Parameter Description

  MGate 4101-MB-PBS Configuration Each Modbus request includes Enable, Modbus slave ID, Function Code, Address, Length, Internal Address, Poll Interval, Swap. Please refer to datasheets or manuals of Modbus slave devices to fill out these fields. Parameter Description Enable The Enable for the transaction: Disable: The transaction is never sent Cyclic: The transaction is sent cyclically at the interval specified in the “Poll Interval”…

• Page 29
  MGate 4101-MB-PBS Configuration After all Modbus requests finish, all the data collected from Modbus should be mapped to PROFIBUS I/O modules for the PROFIBUS Master to use. Click Add to create each PROFIBUS I/O module in the lower table. Then, a dialog which is used to set up the IO module will appear, please adjust the parameters which correspond with the Modbus requests you set before.

• Page 30: Quicklink

  MGate 4101-MB-PBS Configuration NOTE Each “ID” of the commands must be mapped, that is, the commands in Modbus will correspond with the I/O module in PROFIBUS QuickLink The QuickLink is an innovative function to let you configure more quickly and easily, Typically, most PROFIBUS users must spend a lot of time to set up Modbus commands in a PROFIBUS application.

• Page 31
  MGate 4101-MB-PBS Configuration The interface of next dialog is divided into two sections. The upper section is labeled Modbus and will display the details of the Modbus requests which have been learned by the MGate 4101-MB-PBS. The lower section is labeled PROFIBUS Slave and will display the I/O module.

• Page 32: Io Map

  MGate 4101-MB-PBS Configuration IO Map The IO Map is a mechanism which is applied when data from different networks are exchanged via the gateway’s internal memory, so you must define a memory map in the gateway before starting data exchange. Moreover, two networks access the same memory block in a gateway.

• Page 33
  MGate 4101-MB-PBS Configuration The I/O Map function shows the basic I/O mapping relation between Modbus and PROFIBUS. Note that the Modbus related information is marked in <> signs, while PROFIBUS related information is marked in [ ] signs. The I/O Map will show as below figure. Since we set Modbus request with packet length 2 word byte and internal address start from 0;…
• Page 34
  MGate 4101-MB-PBS Configuration Since we set Modbus request with pack size 2 word byte and internal address start from 40000, hence, the MGate will allocate the first 4 bytes from internal memory address (40000~40003). In summary, the Input or Output memory being allocated is depended on the type of Modbus command (read or write). For the PROFIBUS side (I/O module), since the PROFIBUS master are going to access the Modbus data we assigned through the memory areas in the gateway.
• Page 35
  MGate 4101-MB-PBS Configuration The first command is to read Modbus device’s command with function code 03 and the acquired data is to be read by the PROFIBUS master; hence, these data are being placed at Input memory area. Therefore, we set I/O type as Input, and with total 4 bytes data length.

  MGate 4101-MB-PBS Configuration In addition you can select the Paging checkbox to enable the page function, so the utility will insert two I/O word modules into the starting location of the input/output memory bank for separate page functionality. Basically, because one I/O module supports 244 bytes only, the paging function can be used to break through this limit.

Many industrial devices, such as PLCs, DCSs, HMIs, instruments, meters, motors, and drivers, use Modbus as their communication standard.

• Page 54: Requests Need A Time Limit

  MGate 4101-MB-PBS Quick Configuration Exception The master sends a request to the slave. The slave may not support the command or an error is detected, so it sends an exception to the master. Broadcast The master sends a broadcast command, such as a reset command. Every slave on the network complies with the command, and no response is sent to the master.

• Page 55: Diagnose Packet Format

  MGate 4101-MB-PBS Quick Configuration Integrate Modbus Serial and Ethernet with Gateways Ordinarily, Modbus TCP and Modbus ASCII/RTU are unable to communicate with each other. However, with a Modbus gateway in between the Modbus serial network and the Modbus Ethernet network, TCP masters are able to communicate with serial slaves and serial masters are able to communicate with TCP slaves.
