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.

Data area		Type	Range of address	Modbus address	Mapping formula	Modbus data type
M area (5K)	%MX	BOOL	%MX0.0~%MX5119.7	3000~43959	MXm.n: m*8+n+3000	0x
	%MW	WORD	%MW0~%MW5118	3000~5559	MWm: m/2+3000	4x

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.
