AutomationDirect has released the latest addition to its PLC offerings, the Do-more H2 Series PLC. This new PLC line offers features and performance of high-end PLCs for an economical price. Using the DirectLOGIC DL205 hardware as a platform, the Do-more H2 PLC supports all base units, discrete and analog I/O modules available for the DL205 PLC. 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. For larger applications, one or more Remote I/O Master modules installed in the local base can each connect to up to 16 remote I/O subsystems, which can provide hundreds of additional I/O points. Do-more Designer’s built-in simulator creates a virtual PLC so logic can be tested without a PLC present. The tool simulates discrete and analog I/O, with access to timers, counters and control bits, as well as the PID function.
