GE GFK-2193A user manual Read Module Header Reply Data Format for Slave, Word Name Description

4

(Word 9) Local PLC - Memory Starting Address: Word 9 determines the starting address in the local PLC in which the response is to be written. The value entered is the offset (0-based) from the beginning of PLC memory for the memory type and mode specified in Word 8. This offset will be either in bits, bytes, or words depending on the mode specified (for example, if Word 8=16 and Word 9=2, the starting address will be %I9). Valid ranges of values depend on the PLC’s memory ranges.

(Word 10) Response Memory Size: Word 10 specifies the size of the memory block for the response. The Response Memory Size is 25 words. If the Response Memory Size is set smaller than 25, the COMMREQ will fail with a 7 in the COMMREQ Status Word. The user is responsible for assuring that this area is large enough to contain the requested data without overwriting other application data
