Data Contacts/Local Bus
Communication between the fieldbus coupler, controller and the I/O modules as
well as the system supply of the I/O modules is carried out via the local bus. The
contacting for the local bus consists of 6 data contacts, which are available as
self-cleaning gold spring contacts.
Figure 2: Data Contacts
Do not place the I/O modules on the gold spring contacts!
Do not place the I/O modules on the gold spring contacts in order to avoid soiling
or scratching!
Pay attention to potential equalization from the environment!
The devices are equipped with electronic components that may be destroyed by
electrostatic discharge. When handling the devices, please ensure that
environmental factors (personnel, work space and packaging) are properly
equalized. Do not touch any conducting parts, e.g., data contacts.
Do not exceed the maximum total current for I/O modules (5 VDC) via data
contacts!
The maximum permissible total current for internal system supply of the I/O
modules may not be exceeded. The permissible total current is specified in the
technical data of the head station and power supply. The data contacts for
internal system supply can be damaged and the permissible operating
temperature can be exceeded by higher values.
When configuring the system, do not exceed the permissible total current. If there
is a higher power requirement, you must use an additional supply to provide the
system voltage (5 VDC)!
