5-12

- EtherNet/IP Compatible Network Unit DL-EP1 User’s Manual (IB) -

Appendix

The DL-EP1 is capable of the following communication when connected to an Allen-

Bradley SLC5/05 PLC.

• Message communication function: Class3

The size of attribute ID used for SLC5/05 Series is 1 byte or smaller.

The SLC5/05 Series does not support the parameter which contains 2 byte

attribute ID.

• The SLC5/05 Series does not support the cyclic communication

function, but by accessing the DL-EP1's Assembly Object with

messages, control can be executed with the same data type and

procedures as cyclic communication.

• Up to 248 bytes can be exchanged with the SLC5/05 series message

communication.

• Do not exceed this size when exchanging data with message

communication.

• The Assembly Object data size is the same as the cyclic

communication data size set in the DL-EP1 properties. When using

the SLC5/05, confirm that this value is 248 bytes.
