Communicating with the IL Series
- DeviceNet Compatible Network Unit DL-DN1 User’s Manual (IL) -
*1 The function of DL-DN1 only, which responds to explicit messaging synchro-
nously with I/O communication. This function does not guarantee synchronism 
of the whole system, including PLC or master equipment.
