This is a deterministic system be design, and recursive calls may not necessarily complete in a specified amount of time and as such are strongly discouraged. Many PLC manufacturers during project compilation will fail if any attempt at calling a routine recursively, or mocking up a method that in the end does the same thing. It is really to protect you from yourself. Instead, think of a way to perform one calculation of the recursion per PLC scan to get a predictable process. Yes, it will take longer to complete the call, but your process will enjoy a more consistent scan time, which usually means things work more smoothly.
