FC SERIES COMPACT CONTROLLER S (PROGRAMMABLE, STEP OUTPUT TYPE) DATA SHEET The Compact Controller S (programmable type) is a compact single-loop controller using a microprocessor. It accepts uniform signal, and signals from thermocouple and RTD (Resistance bulb) as input, and is equipped with abundant control and computation functions to allow composing a flexible system with a high cost/performance. PNC2 FEATURES 1. Abundant control and computation functions The controller has a variety of control and computation functions in addition to PID auto tuning, and also has a transmission function for data exchange with a host system. 2. Control and computation programming can be made at the site Since the control and computation functions are built into wafers (functional units), an optimum program for the control object can be formed just by keying on the front panel. 3. High reliability LED's (red and green) are used for the bargraph indicator and also for the parameter indication (red), and a nonvolatile memory enables retaining the control and computation parameters even if power should be interrupted. 4. All operation is made from the front panel Operations such as parameter setting, auto/manual changeover are all made from the front panel. 5. Personal computer interface Generic interface availability for personal computer (IBM PC-AT) for supervision, operation, support, maintenance, etc. FUNCTIONAL DIAGRAM Personal computer Other controllers Bargraph indicator Serial communication interface Communication Constant Constant 1 32 terminals External input terminals SUB control block (cascade control, ratio control or schedule control) SV Control wafer PV D/A converter A/D converter Valve opening input (Resistance) (W) Auxiliary analog input 1 (AI1) Auxiliary analog input 2 (AI2) Process variable input (PV) External set point input (CAS) Auxiliary digital input 1 (DI1) Auxiliary digital input 2 (DI2) Auxiliary digital input 3 (DI3) Pulse width input (PI+) Pulse width input (PI-) Manual mode command (SMV) Resistance input converter 4 to 20mA, thermocouple RTD conversion KPV SV MAIn control block (basic control) Control wafer MV Computation wafer Manual Fault Alarm up to 24 wafers usable Manual mode output (M) Fault output (FLT) FLT Indictor H Indictor L Indictor External output terminals Auxiliary analog output 1 (AO1) Compensated PV signal (KPV) Set point transmit signal (SV) Manipulated output (Pulse width) (PO) Auxiliary digital output 1 (DO1) Auxiliary digital output 2 (DO2) High alarm (H) Low alarm (L) EDS11-102e Date Jan. 27, 1999 PNC2 SPECIFICATIONS 1.
