ABB AC500-ECO is a smart solution PLC in meeting the needs of modern control systems that requires small space but high performance. The cost effectiveness for modern industrial automation applications with small flexible PLC solutions often represent the ideal solution by using eco-S500 and S500 I / O modules. Scalable (AC500 platform flexibility) and easy handling through the use of pluggable terminal block makes PLC is widely used and having supporting device as follows:
CPUs have several choices of comprehensive communication with the support of an integrated serial interface makes it easy means of data exchange. Additionally Interface / protocol consist of an Ethernet interface (Ethernet variant CPU) can be used for programming and communication (UDP DHCP protocol, Modbus TCP, HTTP and FTP). COM1 Serial-based data communications interface (RS485) can be used for programming, communication or remote I / O (Modbus RTU protocol, CS31 master remote I / O or ASCII programmed).
1. CPUs
To support the performance of the control system, an eco-AC500 PLC has CPU configuration with the most flexible, economical, inexpensive, easy servicing and all the requirements of modern control system for small applications. Some important features of this CPU such as 128 kB program memory, program processing time of 0.08 microseconds, the CPU module PM556 with 512 kB of program memory, 1 onboard, RS485 serial interface, centralized expandable with up to 10 I / O modules (S500 standard and / or eco-S500 modules can be mixed) and has an optional SD card / SD card adapter for data storage and backup program.CPUs have several choices of comprehensive communication with the support of an integrated serial interface makes it easy means of data exchange.
