Welcome to the Modbus Community, about
the world's leading automation protocol.
Looking for SYSTEM-PKI Companion Document Described in "MODBUS/TCP Security" Specification
Cannot find the [PKI-System] companion document mentioned in the Modbus TCP/IP Security protocol specification (MB-TCP-Security-v21_2018-07-24)

Hi,

I have gone through the Modbus TCP/IP Security protocol specification (MB-TCP-Security-v21_2018-07-24).

In this document (under section 9 System Dependencies), it is mentioned that [System-PKI] companion document includes recommendations that mbaps devices may need to place on the local PKI system for their successful deployment and operation.

I could not find the [PKI-System] document on modbus.org. Please let me know where to find this document.

thanks,
