The SC1400 programmable communication converter functions are shown below.
1.3*RS485 ports COM0, COM1 and COM2, where COM0 is RS232 and RS485. Multiplexing, with communication ports isolated from the interior.
2.1*Ethernet ports with MODBUS/TCP slave protocol support for up to 4 links.
3.The communication converter can be programmed in all standard languages through IEC61131-3, downloaded by RS232 port, and carried out. Data exchange between communication ports.
4. All RS485 support MODBUS slave and free port communication, of which COM1, COM2 with MODBUS main communication function block commands.

SC1400 is a programmable gateway, which needs to be programmed by PCS1200 software, the interface and instruction correspondence is as follows.
The Ethernet port supports ETH.lib library commands for setting and reading Ethernet parameters.
2.COM0 supports RS232.lib library instruction to set and read COM0 parameters, modbus protocol. Slave operations, etc..
3.COM1 supports RS485.lib library instruction to set and read COM1 parameters, modbus protocol. Master-slave operations, etc..
4.COM2 supports RS4853.lib library instruction to set and read COM2 parameters, and modbus. Protocol master-slave operation, etc..
Addressing %MB300 to %MB811 in M Zone is addressable power-down hold for address assignment.
5.Addressing %MB300 to %MB811 in M Zone is addressable power-down hold for address assignment.
The Modbus (Modbus/TCP) protocol address mapping relationship is shown in the following table.

Note: The data area address mapping is the same when three serial ports and one Ethernet port of the SC1400 are used as slaves. . For example.
The bit address is M Zone %MX200.6 and the Modbus (Modbus/TCP) protocol is M Zone %MX200.6. The proposed address is mapped as 3606(200*8+6+3000=3606), the host computer needs to offset 1 bit when reading, that is, 0x3607; the word address is %MW422 in M area, the Modbus (Modbus/TCP) protocol address mapping is 3211 (422÷2+3000=3211), the host computer needs to offset 1 bit when reading, that is, 4x3212; the double-word address mapping is consistent with the first word address, that is, %MD422 mapped corresponding address is 4x3212.
