Which register would you typically increment to keep track of count in programming?

In programming for FANUC robots, registers are used to store different types of data, including counters. The convention is that R[7] is often designated as a general-purpose counter register. This register is typically incremented in looping structures or when an operation is performed a specific number of times, thereby keeping track of how many iterations have occurred.

Using R[7] allows programmers to maintain a count without interfering with other registers that may hold different types of control or status information. Other registers, such as R[0] and R[1], are frequently used for different operational purposes, like storing specific configurations or variables relevant to the current program context. R[10] may also serve specific needs but is less commonly used as a general-purpose counter compared to R[7]. Hence, R[7] is the most appropriate choice for incrementing a count in programming for FANUC robots.
