In input mode (modes 5, 6, 7) or bidirectional mode (modes 8, 9, B) the ibaBM-DPM-S-
64 can write data on the Profibus.
A PC, equipped with an ibaFOB-io card or a combination of ibaFOB-4i and ibaFOB-4o
and an application such as ibaLogic, can send data to a Profibus DP master via the
ibaBM-DPM-S-64. In that case ibaLogic itself is neither a Profibus DP master nor a DP
slave.
Other systems can use this capability, for example SIMATIC S5 or MMC with iba's
ibaLink-SM-64-io interface card or even VME-based systems with iba's
ibaLink-SM-128V-i-2o interface card. These cards also offer a fiber optic input and out-
put link for up to 64 channels.
The advantage for such third party systems is that no Profibus specific driver or GSD-
file is required on their side.
When running in input mode the ibaBM-DPM-S-64 just copies the contents of its
memory, connected to the fiber optic RX-connector, into the DP input data block every
millisecond.
