Frequently Asked Questions
Is the Protocol Implementation Conformance Statement (PICS) a guarantee of complete testing for all functions?
No, the PICS is just an overview. You must consult Appendix A to determine if the complete function or ASDU is tested and supported.
What should be considered when using links like satellite connections for communication?
Long timeouts for t3 may be required in special cases where satellite links or dialup connections are used.
What is the default maximum value defined for outstanding I-format APDUs (k)?
The default maximum range for k, representing the difference receive sequence number, is 12 APDUs.
