ibaPDA Interface: EtherNet/IP (HarmonizedCode:85234910, ECCN:N, LKZ:DE, AG:N)
Communication interface - ibaPDA-Interface for to connect PLC systems via EtherNet/IP
Technical Data:min. interval: 1 msmax. interval: 1000 msNumber of connections/modules per interface: 64
Ethernet/IP supports two module types:
1. EtherNet/IP I/O module:Periodical data transfer (block-transfer, via CIP ForwardOpen)Fixed data structures via standard modulesmax. data transfer to ibaPDA with
ForwardOpen: 499 BytesUsable connection types: unicast / multicast
2. EtherNet/IP Produced Tag:A controller tag can be configured as a "Produced Tag" within RSLogix5000 and Studio5000User-defined data type structure with more capability and flexibility than with EtherNet/IP I/O modulesData must be requested periodicallyMax. size of data structure: 500 bytesUsable connection type: unicast
Special Remarks:Requires an ibaPDA basic licensePlease provide to us the dongle number of the existing PDA license with your order that we can prepare the license extension for your dongleIf there are more than 64 communication connections (modules) required, the interface can be extended with additional 64 interfaces (modules) with the license "one-step-up- Interface-EtherNet/IP". This license extension can be used 3 times per interface and allows in total 256 connections (modules) per interface.For fast data acquisition a timer interrupt with high accurracy is needed. That interrupt can be supplied by an ibaFOB-card, e.g. ibaFOB-i-o.
If no FOB card is in use, only an internal system software timer will be used for generating an IRQ.
However the accuracy and the equidistance of that IRQ depends on the system load. Because of high processor load it could happen that data gets lost during data acquisition.
