Apart from the serial interface the connector X13 provides at ECOVARIO® 6xx additionally two capture
inputs with RS422 signal transmission for rapid capture of process events. Th e capture inputs are not galva-
nically separated and can also be confi gured as digital inputs.
Th e RS485 interface of the ECOVARIO® may as well serve for a 4-conductor (full duplex) as also a 2-con-
ductor (half duplex) connector. Transmitter and receiver of the ECOVARIO® meet the specifi cations of EIA-
RS485 (up to 250 kBaud) and are EMC-protected according to IEC 61 000-4-4.
Th e communication protocol allows network operation with a master (host) and up to 126 ECOVARIO®
units as slaves in an RS485 network. At most 32 participants may take part in one network. Th e network
must have a bus structure.
Th e adress (ID) of an ECOVARIO® is set by the front keys. Each ID may only be allocated once. ID = 0 is
reserved and may not be allocated.
