Syntax
Checksum Start, End |
Ask one axis to return the checksum between Start and Stop addresses from its TML memory |
|
Answer to GetChecksum request |
| Operands | Start: 16-bit unsigned integer value representing the checksum start address |
End: 16-bit unsigned integer value representing the checksum end address
Remark: The online instructions are intended only for host/master usage and cannot reside in a TML program. Therefore their syntax is fictive, the only goal being to identify these commands.
In the Command interprete, you can get a checksum between 2 TML program addresses by sending a GetChecksum request with the syntax:
Checksum Start, End
Where, Start, End represent the start and end addresses for the checksum. The value returned with the TakeChecksum answer, is displayed.
| Description | Through GetChecksum command an external device can check the integrity of the data saved in a drive/motor EEPROM or RAM memory. The memory type is selected automatically function of the start and the end addresses. |
In the expeditor address, bit H – the host bit – must be set to 1 only if the host sends the GiveMeData request via serial RS-232 link. For details, see serial communication protocol description.
The answer to a GetChecksum command is a TakeChecksum, which returns the expeditor axis ID, and the checksum result i.e. the sum modulo 65536 of all the memory locations between the start and the end addresses.
