2.2 Eurotherm 2408CP Outline of Operation When switched on, the controller lights up, goes through a short test routine, and then displays the measured temperature and setpoint. To operate the 2408 there must be power to the furnace or oven, and the Instrument switch must be on.
#EUROTHERM 2408 CONTROLLER MANUAL#
See the instruction manual for the furnace or oven for the overall operating instructions. Furnace or Oven Controls Most Carbolite products are fitted with an Instrument Switch which cuts off power to the controller and other parts of the control circuit. The 2408 does not contain a real-time calendar, and is not subject to century-end date problems. See fig Optional modules are available, in particular: - RS232 and RS432/485 digital communications modules - Analogue communication modules - PDSIO modules for communicate with other controllers of similar or higher specification, for example to allow cascade control - Alarm modules, which can be used to drive visible or audible alarms, or to provide volt-free contacts for customer use. The program can be set to cycle if required. Alternatively the 2408 may be used as a 6-segment programmer, with each segment being a Ramp, a Step, a Dwell, or End. By using one program segment, the control can be extended to include ramp-to-setpoint. indicates the type of temperature response when used in this way. The 2408 features: - Easy use as a simple temperature controller, where on setting the required temperature the controller immediately attempts to reach and maintain it. The 2408CM is like the 2408P4, but is a 20-program model. The 2408P4 is a four-program model in which the programs can be stored independently or can be linked by a call parameter to form a single long program. It is not possible to list all the possibilities in this manual CP Controller The Eurotherm model 2408CP is a digital instrument with PID control algorithms which may be used as a simple controller or a 6-segment programmer.

Special customer requirements may result in changes to the available parameters and the navigation diagram.

#EUROTHERM 2408 CONTROLLER SOFTWARE#
This manual accords with software version 3.06, and to any other software versions where the instrument can be configured in accordance with the navigation diagram and other instructions given in this manual. The manual also applies to the multi-program versions 2408PCM. Controller Nomenclature and Scope of Manual In this manual the controller is called the 2408 or the 2408CP.

The same scaling issues apply as above for reading temperatures.Ī deviceAddress can included in the initial serial object (see notes) for persistence' sake.Ī host of sample settings files for Eurotherm controllers are included (with a device address of 1, but these can be easily modified).1 Operating Instructions Temperature Programmers Eurotherm 2408CP, 2408P4, 2408CM Including 232 and 26 Overtemperature Controller Instructions CONTENTS section page 2408 Description Basic Operation Programming Navigation Diagram Options /26 Description /26 Operation 0 8 Power Limit 2 See also the main manual for the furnace, oven or other product to which the controller is fitted. 'writefullres' can be used again if required for higher resolution. Tempobjcomm('write', serialObject, 1, 2, newTemperature) Higher resolution can be obtained using 'readfullres' instead, and also avoids any scaling issues. if 1 decimal place, 24.2 will be returned as 242. Note that if your temperature controller has decimal places on the front panel, the outputs using 'read' will be scaled. Where data(1) is the current temperature and data(2) is the set temperature. to get the set temperature and the current temperature (process variable) in one go, do:ĭata = tempobjcomm('read', serialObject, 1, 1, 2) Tempobjcomm(commandType, serialObject, deviceAddress, parameterAddress, values)Į.g. Generate the serial object (this one is done on COM7)
#EUROTHERM 2408 CONTROLLER CODE#
This code is derived from that in CO2gui, but is implemented using the native MATLAB serial interface only.ġ. I've currently only implemented it using read and write n words (codes 3 and 16), but I'd be happy to implement the other features, such as fast status read etc. The code is well commented so you should be able to modify it easily. So far only tested with Eurotherm 24 temperature controllers but they all use the same language so it should be widely applicable. Currently only tested with serial RS232, but should work the same with RS485 if wired correctly. Reads and writes information to Eurotherm controllers via Modbus RTU protocols.
