The Do-more H2 Series PLC line offers features and performance of high-end PLCs for an economical price. The H2 CPUs offer four times more program memory, nine times more data memory and operate at speeds up to 20 times faster than current DL205 CPUs. A Do-more CPU installed in a DL205 9-slot base supports up to 256 I/O points. The I/O Configuration window performs full auto-discovery of all I/O modules in the local base, simplifying system configuration. Embedded communications ports (serial, USB and Ethernet) reduce system cost and space. "Device abstraction" makes it easy to connect external devices by allowing the user to assign logical names and then refer to those names throughout the program code for ease and clarity.
