Field of application
The system consisting of IM 260, IM 261 and interconnecting cables is an
expansion option that you use to split the System 200V over up to 4 rows.
This system may only be installed in a centralized System 200V where a
PC 288 or a CPU is employed as the master station!
For bus expansion purposes you always have to include the basic interface
IM 260. The basic interface may then be connected to up to 3 additional
System 200V rows by means of the appropriate interconnecting cables and
the IM 261 interfacing module for rows.
Certain rules and regulations have to be observed when the bus expansion
modules are being employed:
•
The bus expansion may only be used in conjunction with the PC 288
(VIPA 288-2BL10) or a CPU (combi-CPUs are also permitted). The
system must never be employed in decentralized systems, e.g. behind a
Profibus-DP slave!
•
The system caters for a maximum of 4 rows.
•
Every row can carry a maximum of 16 peripheral modules.
•
The max. total quantity of 32 peripheral modules may not be exceeded.
•
In critical environments the total length of interconnecting cables should
not exceed a max. of 2m.
•
Every row may derive a max. current of 1.5A from the backplane bus,
while the total current is limited to 4A.
•
At least one peripheral module must be installed next to the IM 260
basic interface!
