System overview, CTEL system Overview CTEL system Festo can assist you in solving your automation task at the machine level with the aid of valve terminals and I/O modules. The CTEL master module from Festo permits connection of devices with an I-port interface (I-port devices) to a CPX system.
– Relay plates, pressure zone separation plates and blanking plates can also be integrated. I-port input modules – Make available inputs for connecting sensors and enable interrogation of cylinder positions, for example. Other I-port modules Tab. 2.1 Festo – P.BE-CPX-CTEL-EN – 1411a – English...

The CTEL master module has 4 I-port interfaces. I-port is an interface for the exchange of serial data for the connection of decentralised function modules (devices) from Festo at field level. It is based on the IO-Link technology and is compatible with it in certain areas.
Tab. 2.2 2.2.3 I-port connecting cables Operation in accordance with specifications is guaranteed only if original Festo connect ing cables are used. For operation in accordance with specifications, the maximum length of the I-port con necting cables must always be observed (è 3.3).

The I/O lengths listed here are the sum of the bytes available for all I-ports together. Which of these configuration presettings the CTEL master module uses can be determined manually (through the user) or automatically (through the module itself ), dependent on the operating mode. Festo – P.BE-CPX-CTEL-EN – 1411a – English...
With the DIL switches 2.1 and 2.2, the I/O length, i.e. the available I/O bytes per I-port, are determined in the manual configuration (è Tab. 2.6). In automatic configuration, the setting of these two switches is not relevant. Festo – P.BE-CPX-CTEL-EN – 1411a – English...

A total of up to 4 I-port devices can be connected to one CTEL master module. The devices are connected via Festo I-port connecting cables to the CTEL master module (è 2.1 Overview CTEL system and 3.3 I-port connecting cables).
The total current requirement of the CPX terminal and the CTEL system, as well as the limit values for the maximum current intensities, must be taken into account in the design of the voltage supply (è 3.5.2 Determining the current consumption). Festo – P.BE-CPX-CTEL-EN – 1411a – English...
Observe the notes regarding selection of the power supply unit in the CPX system description (P.BE-CPX-SYS-…). If you are using I-port output modules with a separate load voltage connection, take into account the corresponding current consumption when selecting a power supply unit.

Since no individual I/O lengths are possible with the manual configuration, an I/O length of 4 bytes per I-port, that is 16 bytes (for all I-ports together) must be selected (switch S2.1 to “OFF”, S2.2 to “ON”). The configuration presetting selected through this is thus 16 bytes I/16 bytes O. Festo – P.BE-CPX-CTEL-EN – 1411a – English...

To make a connection set-up between the CPX terminal and higher-order controller possible, the manu al configuration presetting of the CTEL master module must agree with the respective entry of the cor responding fieldbus configuration file (è 3.6 Connection with the host system).

Observe the notes on “Force”, “Idle mode” and “Fail safe” in the CPX system de scription and in the description for the operator unit if the CPX bus node used sup ports these parameterisation types. Festo – P.BE-CPX-CTEL-EN – 1411a – English...
The “Force” function can also be called up via the “Monitoring ...” menu. This function allows you to force signal statuses during the commissioning phase for test purposes. The same representation of the I-port devices also applies correspondingly to the “Idle mode” and “Fail safe” functions. Festo – P.BE-CPX-CTEL-EN – 1411a – English...
Commissioning Commissioning with the Festo Maintenance Tool software (CPX-FMT) The PC software CPX Festo Maintenance Tool (CPX-FMT) can also be used for commission ing, parameterisation and extended diagnostics of the CTEL master module. You can find the current software version in the Internet (è www.festo.com/sp).
Advantage: Fast “on-site” error detection; diagnostics also possible from a higher automation level Tab. 5.1 Diagnostics options Note The available diagnostic information may depend on the settings of the CPX bus node or on the parameterisation. Festo – P.BE-CPX-CTEL-EN – 1411a – English...
Within a CPX terminal, diagnostics/error messages with reference to inputs have priority over diagnostics/error messages of outputs. This principle of error prioritisation also finds use in the CTEL master module in the I/O mixed operation. Festo – P.BE-CPX-CTEL-EN – 1411a – English...
