FGs and FGR series — volume and ultra-slim PLCs

Two families cover the volume and the ultra-slim ends of the range.

FGs is the volume line: AC 100–240 V supply, 16 to 64 points, compiled code more than ten times faster than an interpreting controller and full password protection. Its envelope covers pulse and counting to 200 kHz, 2–4 pulse channels with real-time speed and position adjustment, interpolation and electronic cam, 8 expansion modules and more than 20,000 lines of user program. RS232, RS485, USB and Ethernet carry free-port and Modbus protocols, with Modbus RTU networks over RS485 reaching 127 devices. Main units run from FGs-16MR-AC to FGs-64MT-AC between 109.5 × 92 × 80 mm and 216 × 92 × 80 mm.

FGR addresses machines with very little panel depth: 25.2 mm wide, 92 mm high, 63.4 mm deep and 102 g, at a favourable price/performance ratio. FGRB-C8X8T-2/2 provides 8 inputs and 8 transistor outputs with two counter and two pulse channels at 200 kHz; FGRS-C8X8T-4/4 uses the high-performance CPU to double this to four of each with two AB-phase channels; FGRB-C8X6R has 8 inputs and 6 relay outputs. Interfaces are one mini RS232 port at 1200–115200 bps, one RS485 port at 4800–115200 bps and USB, with no Ethernet.

The FGs designation uses five fields: FGs, I/O total, output type (MR relay, MT transistor), supply (A for AC) and architecture (C for compiled). FGs expansion modules add a C suffix at 109.2 × 61.7 × 80 mm and 250 g.
