CRC16
(var, count) {* Applicable only to M+ PLC with firmware r44 or higher}Purpose | This function returns the computed CRC16 for a range of integers starting from variable "var" with the range indicated in the parameter "count". CRC16 is a 16-bit version of "Cyclic Redundancy Check" - a popular mathematical formula for checking error in a data stream. |
Examples | DM[100] = CRC16(DM[5],8) X = CRC16(RELAY[2],4) |
Comments: | CRC16 for DM[5], DM[6]
..DM[12] will be assigned to
DM[100] CRC16 for RELAY[2], RELAY[3], RELAY[4] will be assigned to X. |
