The system centre (complete design) in the E*LDS system:
The system centres in the Virtus 5 series are compatible with the CI 5x00/CI 4x00/CI 3x00 and are intended as
replacement device for these predecessor models.
The CI 4000 series does not have any direct interfaces to the old LDS1 system (VS 1000 / VS 2000
and CI 320 / CI 322)! LDS1 gateways that are connected via the COM3/MODBUS interface are
required for the inclusion of LDS1 case controllers, for details see chapter Integration of case
controllers of the E*LDS system.
