In a circuit program, you can only configure one data log to record the actual values of function blocks, and the following memory areas:
I
Q
M
AI
AQ
AM
For digital I/O and memory, you must log data in groups of eight bits, for example, I1 to I8, Q9 to Q16, M17 to M24. For analog data, you select one value to log, for example, AI1, AQ2, or AM1. You configure function block values in groups of eight bits or single values, depending on the value type (digital or non-digital).
You can log a maximum of 32 items (analog values or eight-bit digital groups) in the data log.
You can only configure the data log from LOGO!Soft Comfort. You can not create, configure, or delete the data log from a LOGO! device.
