The device type, when directly named, must be supported by the driver. List here:

Specicically the KM1002 will not work in any case, as it is not an EtherCat Module but rather a regular "Busklemme" which uses the old Beckhoff K Bus. You could try to use a BK series EtherCat KBus coupler:

However, you will have to create your config with the generic driver and it is going to be cumbersome at best (search BK1120 in this board - I tried and got help). Honest opinion: Don't. Sell the Module, buy an EL series module.
