I have a question about Modbus TCP automatic mapping. This is happening on AS 6.7, but I’ve also observed it on previous versions.
If I correctly declare the settings, address, and tags for a group of registers, and later rename the “Name” of an already declared channel (e.g., channel 1), the change is not automatically propagated to the IOMAP: the old declaration appears to be lost, and the new name/tag shows up empty in the I/O mapping.
However, if I search inside iomap.iom, I can still find the old declaration there. So I’m aware of what’s happening, and as a workaround I edit iomap.iom directly, but this behavior seems wrong — I’d expect the rename to update the existing mapping automatically instead of orphaning the old entry.
Has anyone else run into this? Is this a known limitation, or is there a proper way to rename a channel without losing/duplicating the mapping?
Thanks in advance, Ennio
