• Application Example
The following example checks the data in addresses 0010 to 0012 (hex).
1) Assume that the following data is initially in memory.
2) The Data Check command is executed to calculate the check code for 5 bytes beginning with
address 0010 (hex). The CRC Code 5CD6 hex calculated from the data “123456” is written to
addresses 0013 and 0014 (hex).
3) The Data Check command is executed to verify the check code for 5 bytes beginning with address
0010 (hex). If the data is normal, the Normal End Flag in Unit Status (CIO n+7, bit 01) is turned ON.
If the check codes are not the same, the Error End Flag (CIO n+7, bit 02) in Unit Status is turned ON.
