ACCU
The accumulators are registers on the CPU and serve as buffers for load, transfer,
compare, calculation and conversion operations.
Backplane bus
The backplane bus is a serial data bus over which the interface module IM 151-2
communicates with the electronics modules and supplies them with the required
voltage. The connection between the individual modules is established using the
terminal modules.
Bus
Common transmission path to which all nodes are connected. It has two defined
ends.
With the ET 200, the bus is a twisted-pair cable or a fibre-optic cable.
Bus connector
Physical connection between the nodes and LAN cable.
Bus termination module
The ET 200iS distributed I/O station is terminated by the bus termination module. If
you do not insert a bus termination module, the ET 200iS cannot be operated.
Chassis ground
Chassis ground includes all the interconnected inactive parts of equipment that
must not carry a hazardous voltage even in the event of a fault.
