Paul Rylatt Posted October 23, 2012 Report Share Posted October 23, 2012 I am attempting to use the RFC-1305 block in a program on a V130. Currently, the block cycles every 5 seconds. This seems somewhat excessive. I would like to make it adjustable so that the user has control over the cycle time and can eliminate unnecessary clock server calls. Another problem is that if NIST servers are used, pings faster than every 10 seconds are considered denial-of-service attacks and geographically remote PLCs without an intervening local PC clock would not be able to use UTC.
