How can I monitor module and slave status with the MVI56-PDPV1 and other PDPMV1 PROFIBUS master modules? |

The PDPMV1 operating state is stored in the MVIxxPDPMV1.Status.Fieldbus.FB_op_state tag: 00 = Offline 40 = Stop 80 = Clear C0 = Operate To determine slave status, the MVIxxPDPMV1.Status.Fieldbus.FB_Slave_Data_xfer array contains a bitmap of all the PROFIBUS slaves currently in communication with the PDPMV1 master. The data type is SINTs, so each element in this array contains bits representing 8 PROFIBUS addresses. For example, if bits 0 and 3 are set in MVIxxPDPMV1.Status.Fieldbus.FB_Slave_Data_xfer[0], slave addresses 0 and 3 are communicating successfully. Slave_Data_xfer[1] would contain the booleans representing addresses 8-15, Slave_Data_xfer[2] would contain the status bits for addresses 16-23, etc. A simple XIC or other RSLogix function can be used to monitor the communication status of any slave attached to the PDPMV1 master. Note that with the MVI56-PDPMV1 using the Legacy AOI and with the MVI69-PDPMV1 these status tags are continually updated automatically. If using the MVI56-PDPMV1 with the Flex AOI, the toggling the MVI56PDPMV1.Command.GetStatus tag is required to trigger an update for this or any other status information. |
