Hello everyone, i have problem with this Ramsey Micro-Tech 9101 scale that i installed. Everything is okey with connection i dont have any error he picks all weights and everything is nicely showing on screen. The problem that i have is when i want to take data from scale to plc. - connect Ramsey with profibus to plc - installed gsd file for 9101 version
- made slave address 22 on scale and in program - made 48 in/out words - made on scale that he give display values Everything is great no errors and everything is fine, but then when i take QW from Ramsey he all wheys gives me 0. I made it like this: First i read input/output word from Ramsey in Tia portal I: 376....471 Q: 256....351 then i found tabel from Ramsey with offsets that gives me Load, Speed, Rate and they are Rate 33, Load 35, Speed 37 then i took QW256 + 35 for load and i entered QW291 in Force Table just to see what he will give me but like i say he give only 0 and for each number i enter he gives 0. Then i read i manual that you need to first write some sort of request so that Ramsey can give you value on output. So what i did i fallowed guide it say: 00 -> scale 1 01 -> scale 2 etc and for second part of hex you chose what you want to read i mean hat block: 00 is i/o, alarms etc the thing i need 01 is batch read block 02 status etc. so i took 0000 basicly 00 for only having 1 scale and 00 because i want i/o, alarms etc. put that in input in force table like IW376 and force it with that hex(0000) but it still dont give anything on QW only 0. I will attach cutted PDF part for profibus so you guys dont need to look for it it is only 14 pages. If anyone can help me it would be great! Thanks in advance! mskrpan1 AttachmentRamsey-Micro-Tech-9101-9201-Reference-Manual.1.pdf (493 Downloads) |
