Currently I have two (three in the near future) 319F-3 PN/DP CPU's that need to communicate.
PNPN couplers are not possible because of distance.
I currently use TCON - FB65 method with FB63/64 to send / receive data.
This function does work.
I previously used the SFB12 + 13 method by setting up the S7 connection inside Netpro on another project. Now is this method more secure?
I just need the more bulletproof option
