- Does any one know if S7-300 or S7 400 range of PLCs support 9th Bit Interrupt in their Serial Ports, and how do we take this into account so that data & the application can be on Interrupt based instead of scan based on S7 300 / 400 ?
- What would be the cable diagram to support 9th bit configuration?
- Any write up such implementation ?
- Does DP-RS232 module of Siemens also support this feature over profibus ? (It may need more explanation , but if any one can let me know it would be wonderful) ?
- What Industrial Known Serial devices (A small list) are supporting 9th bit Interrupt on RS232 ?
- Any Application example or implementation would be of great interest !!
Thanks for reading and thinking on my behalf!!
