Performance characteristics:
SM1 Series PLC is to satisfy the market for 10 points, 14 points, 16 points, 28 points (new) -24 points, 16 points within the low-cost, high-performance needs of the PLC design, development of new products.This series of products have more communication function, 16 points, 24 points each with two communication port (one for the RS-232C, one for the RS-485), to make communication more convenient.The product can be widely applied to a metallurgical, coal, chemical, textile, food industry, production machinery, industrial assembly line, all kinds of machine tools, industrial control devices.
Use of Flash ROM, power failure memory without batteries
Reserve 2 communication port RS - 232C and RS-485
Through the RS-232C communication port can be with the programmer S-20P, S-10HP, S-100HP communications, but also with the Host Computer, S Series PLC, displays etc. CCM protocol communications (maximum 90 units, SM1 series PLC only from the machine function), no agreement is communication;
Through the RS-485 communication port with other devices can be CCM protocol communication, but also constitutes a network with the SM1 Series PLC (maximum 32 units). |
