Abstract
Illustrated is an I/O module which is configured for cyclically transmitting and receiving telegrams, wherein an area in which a data record can be transmitted in its entirety is provided in the telegrams, as well as an area capable of containing only a part of a data record, so that said data record is transmitted, distributed over several telegrams.
Claims11
A system comprising:
- a plurality of sensors and/or actuators;
- an input/output module (I/O module);
- and
- a control module,
- wherein the I/O module cyclically derives, on the basis of a parameter set, a state data record from measurement signals of the sensors and/or cyclically derives control signals for controlling the actuators from a control data record;
- and
- wherein the control module cyclically receives first telegrams of a constant size with one state data record each from the I/O module, and/or for transmitting second telegrams of a constant size with one control data set each to the I/O module,
- wherein the I/O module transmits diagnostic data regarding the function of the I/O module, of the sensors and/or of the actuators, distributed over several first telegrams, to the control module, and/or
- wherein the control module transmits, distributed over several second telegrams, data describing a parameter set to the I/O module.

A method for communicating data between an I/O module and a control module, the method comprising:
- cyclically transmitting first telegrams of a constant size from the I/O module to the control module and second telegrams of a constant size from the control module to the I/O module;
- reserving, in each of the first telegrams, a fixed number of first bits that are used for the serial transmission of a first data record;
- and
- reserving in each of the second telegrams, a fixed number of second bits that are used for the serial transmission of a second data record.
