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.
