Product Manual Excerpt

SVCREQ #23: Read Master Checksum Use SVCREQ function #23 in order to read the Master Checksums for the User Program and the Configuration. The SVCREQ output is always set to ON, and the output block of information (see below) starts at the address given in parameter 3 (PARM) of the SVCREQ function. In the instance when a Run Mode Store is active, the Program checksums may not be valid until the store is complete. Therefore, two flags for when the Program and Config- uration checksums are valid are given at the beginning of the output parameter block. For this function, the parameter block output has a length of 12 words. Format of the information is shown below: Master Program Checksum Valid (0 = not valid, 1 = valid) Master Configuration Checksum Valid (0 = not valid, 1 = valid) Number of Program Blocks (including _Main) Size of User Program in bytes (DWORD Data Type) Program Additive Checksum Program CRC Checksum (DWORD Data Type) Configuration Additive Checksum Configuration CRC Checksum (DWORD Data Type) Size of Configuration Data in bytes Word Address Output Parameter Block address + 2 address address + 1 address + 3 address + 5 address + 6 address + 8 address + 9 address + 10 Example 1: In the following example, when input %I0251 is ON the Master Checksum information is placed into the parameter block and the output coil (%Q0001) is turned on. The pa- rameter block is located at %R0050
