Hi, short facts / hypothesis: - data mapping of process data from non-rexroth ethercat slaves can not be done byte-wise. - This is maybe an issue of the ctrlx I/O Engineering software (which is an talored version of the codesys version) Balluf IO-Link devices in Codesys V3.5 SP16.2 can use a feature to get the Process Data as type Bytes which creates Mapping nodes that would help ease the mapping process into PLC program variables. See attached picture. Note: Of course a so-called ESI device description file is installed in ctrlx I/O Engineering to get the fieldbus module and also the types of modules to be plugged into the bus, this file is available for download on Balluf website under the EtherCAT page https://www.balluff.com/en-de/products/BNI0077. When Installed on Bosch Rexroth I/O Engineering tool software, The feature of BYTE type process data doesn’t show up (Grey IO logo) [Figure 2] and also no Mapping-Nodes available [Figure 3]. So the bit mapping has to be done BIT by BIT example [Figure 4]. So is this an issue of "there is no gray I/O icon" available when using ctrlx I/O Engineering vs. codesys? In the codesys installation every possible slave device config is offered two times: one time with "bit-wise-mapping" other time with "byte-wise-mapping" Thanks for any hints. BR Andreas
