jinga Posts: 26 Rating: (2)	Hi! I've created a FB with put instructions, REQ parameter is given by a 1Hz clock, and ADDR_1 and SD_1 are configured as pointers to DB. The data I'm trying to pass from one cpu to another is a vriable with format "real". The pointers are defined on the basis of the example of put/get program in this forum. However, when I run the program, I always get status 16#0019. What am I doing wrong? Thanks

(if you use S7-1500: go in the configuration to Security and check the button "allow PUT/GET communication")
	Best Regards, Fafner

Pittiplatsch Posts: 1368 Rating: (126)	Hello, just for information, the status at PUT/GET must be read as "decimal". So Status 16#19 is 25(dec) and this means: Job is in process. the status shows only the true value for one cycle. So please transfer the status in another variable in case of errorbit = true. The blocks, put/get access must be typ "standard" (not optimized).

jinga Posts: 26 Rating: (2)	so: -the cpus are 1214c dc/dc/rly and 1215c dc/dc/rly -the software is tia portal v11 update 5 -by pressing f1 there is no error 19 in the list! Pittiplatsch The blocks, put/get access must be typ "standard" (not optimized). by saying this what do you mean? the DB from which I read/write are already standard and not optimized, there is something else I should change?

Pittiplatsch Posts: 1368 Rating: (126)	Please read my last post again the status at PUT/GET must be read as "decimal". So Status 16#19 is 25(dec) and this means: Job is in process. the status shows only the true value for one cycle. So please transfer the status in another variable in case of errorbit = true. if your DBs are "standard", everthing is ok in this case:-)

Pittiplatsch Posts: 1368 Rating: (126)	And another thing to try: can you remove the 1Hz on the REQ and try to call the PUT/GET with only one REQ = true?

jinga Posts: 26 Rating: (2)	yes, I did try but in that case I always get status 0000 (which is fine) but values are never written to the other cpu and, of course, the instruction never reaches the value "done". I checked and it reads the values correctly, but does not write them. The pointers i use are the same: P#DB8.DBX0.0 BYTE 4 so I still don't know what is not working...

William_B Posts: 5225 Rating: (1195)	jinga so I still don't know what is not working... Thanks to Pittiplatsch for all the help given already. Please jinga may we have a piece of the program as to assist you better. I propose the smaller version you are using to test communications. I am sure with that, my friends will be able to be of more help. PS: That is to say if the problem is software and not hardware or hardware configuration. Regards, w
