Small PLC AC31 series 40…50
The AC31 offers compact, high performance CPUs with various configuration options, including decentralized networking.
Both series 40 and 50 utilize the same AC31GRAF software which conforms to the IEC 61131-3 standard.
All devices have a very small footprint and offer high levels of functionality with up to 1 MByte of user memory as well as up to 60 integrated I/O connections (analogue and digital) and two serial interfaces (both of which are configurable for MODBUS or ASCII).
There is also a plug-in "smart media" card for saving user programs or for data storage.
An additional two communication interfaces with their own processors are also available integrated within the CPUs.
Hence the customer can choose varying combinations of
integrated field communications network protocols, e.g.
Ethernet + PROFIBUS DP, ARCNET + CANopen or CANopen
The communications couplers are integrated within the standard housing of the CPU in order to save space. Tools for the configuration of the field buses used are already an integral part of the software package 907 AC 1131.
There is a very high degree of integration available across all three series of CPU’s.
