- Red external fault LEDs
- Green LEDs for digital input status display
- Yellow LED for indicating backup operation
High-performance measured data acquisition:
The module has 16 analog inputs for analog value acquisition and disturbance variable input as well as 1 additional analog input for temperature compensation when used with thermocouples.
Various encoders can be used:
Thermocouples, Pt 100, voltage encoders, current encoders.
Extensive I/O:

The 24 V DC supply for the actuators is applied externally.

Configuring package

The configuring package required for configuration comprises:

Manual
Parameter assignment screen forms
Standard function blocks for data exchange with the CPU

Функции

The FM 455 has 16 separate closed-loop control channels. The controllers display the following features:

Prefabricated controller structures for:
- Fixed setpoint control,
- Cascade control,
- Ratio control,
- 3-component control.
Choice of modes:
Automatic mode, manual mode, safety operation, follow-up mode and backup mode
Sampling time (depending on the resolution of the analog inputs and the compensation input):
- For 12 bit: 20 to 180 ms.
- For 14 bit: 100 to 1700 ms (depending on the number of enabled analog inputs)
2 control algorithms:
Self-optimizing temperature algorithm, PID algorithm
User-friendly controller optimization:
The self-optimization function for the temperature algorithm is stored on the module and can be automatically activated in the case of setpoint changes of more than 12 %. the PID control algorithm is optimized using the parameterization screen forms in the configuring package
Backup mode:
In the event of CPU failure or CPU Stop, the controller can continue to operate independently.
Disturbance variable input:
the analog inputs can be used for feedforward compensation in addition to actual value acquisition, if desired.

Function blocks
PID_FM	Closed-loop control with the FM 455: The interfacing of the FM 455 with the user program supports: The modification of control parameters, setpoints, control outputs The operation of, for example, setpoint and manual control outputs The monitoring of, for example, actual value and setpoint value
FUZ_455	Reading and writing the parameters of all temperature controllers; the transfer of identified control parameters.
FORCE455	Commissioning of the FM 455: Supports the simulation (forcing) of the analog and digital input values
READ_455	Supports the reading of analog and digital input values
CH_DIAG	Commissioning of the FM 455: Reads others channel-specific parameters from the module
PID_PAR	Supports the online modification of other parameters that cannot be entered with the FB PID_FM
CJ_T_PAR	Supports the online modification of the parameterized reference temperature

Temperature controller with integrated self-setting

The temperature controller with integrated self-setting is suitable for controlled systems where the entire process has approximately the same temperature when the setpoint is reached, as is the case in water bath controls, steam boiler controls or injection molding machines.

The procedure is unsuitable for controlled systems where the temperature in a significant portion of the process still varies significantly after the setpoint has been reached, as is the case in furnace controls where the air heats up and the temperature is measured. When the air temperature has reached the setpoint, the furnace and its contents can still be cold.

Parameterization

A configuring package is available for parameterizing the FM 455. This contains all the screen forms required for configuring, parameterization and startup.

Detailed online Help is available for all screen forms.

The parameterization screen forms are called up from STEP 7 following installation.
