Description
The external module JUMO ER8/EL8 expands the instruments
JUMO DICON 400/500/401/501,
LOGOPRINT 500 and JUMO LOGOLINE 500/500d by eight relay
outputs (ER8) or logic outputs (EL8). The functions of the outputs are
defined in the instrument that is connected, or via the setup
program. Communication takes place through the serial interface.

If a communication via PC-Interface is established while
operating the ER8/EL8 with the LOGOLINE 500/500d,
DICON 400/500/401/501 and IMAGO 500 (also COM1), the
device will interrupt the data transmission and the fault
indicator will blink.
