Option packages
IONs – Input-Output Nodes
SIPLUS CMS offers "IONs" for acquiring measured values.
These are hardware or software modules that acquire the mea-
sured values. The software nodes, ION’s are included in the
standard software X-Tools when this option is ordered. The hard-
ware for ION’s should be ordered separately, it is not part of the
optional package in CMS Basic. Such hardware depends of the
project configuration.
With the numerous hardware IONs in the SIPLUS product range,
measured values can be acquired directly where they arise. This
avoids incorrect interpretations which may result due to the time
taken to transmit via a controller. Sampling rates of up to 40 kHz
(analog) or 50 kHz (binary) are possible using hardware IONs.
Software IONs
SIPLUS CMS records the data directly from the SIMATIC S7 and
SIMOTION controllers using appropriate software IONs (Input-
Output Nodes). The sampling rate using software IONs depends
on the controller platform used. A "cycle-synchronized" trace
can thus be achieved.
PROFIBUS ION
The PROFIBUS ION, also known as "Spy", is particularly versa-
tile. This module can be used to record any values which pass
via the PROFIBUS. The spy is a totally passive node and affects
neither the bus nor the cycle time of controllers. The sampling
rate that can be achieved is the PROFIBUS cycle.
The PROFIBUS ION should be ordered separately.
Selection criteria software ION characteristics:
•
For an integrated SIMATIC S7 or SIMOTION complete solution
•
Up to 172 channels (signals or values) per controller
•
Sampling rate up to the minimum cycle time of the controller
(depending on the quantity structure)
•
No additional hardware components required
•
Communication via existing Ethernet interfaces
PROFIBUS ION (PROFIBUS Spy) characteristics:
•
Independent of the controller used
•
Expansion capability regarding the number of signals
•
Sampling rate in the PROFIBUS cycle
•
No resources required on the controller side
(cycle time, memory)
•
Communication over IEEE (interface required in the PC)
