1. 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 mod- ules. The CTEL master module from Festo permits connection of devices with an I-port interface (I-port devices) to a CPX sys- tem.

For connection of the I-port devices to the CTEL master • module, use only the special I-port connecting cables from Festo (see also appendix A.3). Observe that the length of the I-Port connecting cables is • limited to a maximum of 20 m.
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 (see section 1.1 and section 2.3). If an error occurs on several devices simultaneously, only the diagnostics/error message of the device with the highest priority is passed on (see section 4.2.1).
