PROFILE
GFXTERMO4 is a multi-loop control system that controls four process loops in a completely independent manner. Configuration of I/O resources is very rapid and flexible thanks to a programming tool that guides the user in the selection of parameters.
Each control loop has:
• Process input
• Input for external CTs or CT / linear
input
• Control output
• Cooling output
Other auxiliary I/Os:
• Two digital inputs
• Two relay outputs
The use of two independent serial ports provides efficient communication ability.
The two serials are defined as follows:
• “local bus” to create a GFXTERMO4 network and connect it to an operator panel or industrial PC.
Uses Modbus RTU protocol and reaches a speed of 57,6 Kbps.
• “field bus” to integrate with architectures that already use industrial field buses such as: Profibus DP, CANopen,
DeviceNet, Modbus RTU, Ethernet
Modbus TCP, Ethernet IP, EtherCAT,
ProfiNET.
The presence of “intelligence” directly on the board lets the user create fully independent and reliable controls.
The device installs on the DIN rod or with two M4 screws.
MODELS
GFXTERMO4
A single model is available for the control of four control loops.
INPUTS
Manual-Automatic operation, or to reset the alarms latch. The operation of both inputs is configurable.
External/ auxiliary analog CTs (option)
An additional four inputs to read external
CTs for simultaneous check of currents delivered to each zone, with consequent control of alarms (HB...). As an alternative, you can order the inputs to read four temperatures (CT) or linear inputs.
OUTPUTS
The functions are configurable via software.
Heating control
Each zone has a digital output configured for heating for direct control of solid state power units (SSR).
Analog process inputs
The four process inputs are universal and can connect various signal types:
- thermocouples,
- resistance thermometers,
- linear in voltage and current.
The inputs are configurable via software.
Not external adapter shunts are required.
Cooling control (option)
Each zone has a digital output configured for cooling. Four output types are available: relay, logic, triac, continuous.
Alarm
Each unit has two relay outputs configured as minimum and maximum alarm.
Digital inputs
There are two digital inputs.
These inputs can be used to select one of the two presettable setpoints, or to select
SIGNAL LEDs
Eight signal LEDs provide immediate diagnostics of operating state.

O3

A meaning other than default can be assigned.
CONFIGURATION
The unit is configured by setting simple parameters.
No knowledge of programming language is needed.
The following can be used for configuration:
• GFX-OP accessory
• Winstrum software tool
• Operator terminal, industrial PC or PLC.
FUNCTIONS
Alarms
8 alarm limits are available, freely assignable to each channel or to all channels
(in AND / OR logic) and configurable as absolute, deviation, direct, reverse, window, latching or not, disabled at power-up.
Diagnostics
In addition to generic alarms, efficient diagnosis of the control loop lets the user prevent breakdowns and take timely action, for example in case of broken probe or load.
The LBA alarm provides precise control of the control loop.
With the optional current transformer, you can directly monitor the load and activate the HN alarm in case of power failure or short circuit of the solid state power unit.
Software can be used to define the state of the alarm outputs or a preset power value to be supplied in case of broken probe, thereby assuring the unit’s continuity of
Control
Advanced control algorithms provide service.
excellent control of process variables.
Several types of control are available: ON/
OFF, P, PI, PID (heat or cool alone as well as double-action heat+cool).
Cooling can be set by specifying the cooling fluid used: air, oil, water.
Calculation of the best process parameters is extremely quick and effective thanks to the use of sophisticated automatic tuning.
The use of advanced tuning lets the user check the most correct PID parameters under all conditions.
Tuning
• Self-tuning: calculation of PID parameters at system power-up.
• Continuous auto-tuning: continuous optimization of PID values
• One shot auto-tuning: modulation of output and automatic recalculation of PID parameters from event
Special functions
• Soft-start: slices power based on a set time
• Software off: disables control with consequent deactivation of outputs
• Input/output control: activation of outputs and control of inputs can be disengaged from internal firmware
• Simulation of four independent Geflex units (without cutting power).
COMMUNICATION PORTS
The unit is supplied with one communication port [PORT 1] that is used as a local bus for the connection of multiple
GFXtermo objects connected to an operator panel or to an industrial PC.
In addition to this port, the current range of
Geflex products can be connected via the
10-pin connector.
A second communication port [PORT 2] is available on request, configurable with the most popular industrial protocols:
CANopen,
DeviceNet,
Profibus DP,
Modbus RTU
Ethernet Modbus TCP,
Ethernet IP,
EtherCAT,
ProfiNET.
Network addresses
The network node address is assigned in a positive manner with two rotary selectors.
