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.

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.

- Page 37 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.
- Page 38 MGate 4101-MB-PBS Configuration The IO map interface shows input and output memory array. The row unit is internal address and the column unit is byte number. Each column has a length of 20 bytes. Each cell is showed as the following table: Modbus Mode Command The Format Meaning...

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. -

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.
