I connected encoder but nothing happens, i have an incrementa encoder 1024 PTS, 5-30 V dc. In hardware configuration, when i want to see module information about encoder module, nothing happens, compare with DI module. I tried to make settings like to "SIMATIC ET 200S TEHNOLOGICAL FUNCTIONS" BUT NOTHING. this is first time when i try to make a project from zero. if someone can guide me with some one information. thanks you in advanced for the cooperation, best regards, myhay ene

myhaye Posts: 45 Rating: (0)	hello, My encoder istype XCC-1510PS11Y, and the connection were made like in attachement: - the encoder has the following wires: - A negate; +V; 0; 0 negate; B; B negate; R; A; R; 0V; 0V; +V in this order, 12 3 4 5 6 7 8 910 11 12 i used 5, 8, 12 and 11. best regards, myhay ene Attachment wire.JPG (209 Downloads)

Make shure A and B show more than 12V (against ground and 0V) as high signal. (You can use a normal (digital) voltage meter, just turn the encoder slowly until you have a high signal) According to the attachment, I'm not shure the encoders "XCC 15......Y" give enough voltage to the outputs (additional note: RS422 - 5 V.) Maybe you need the 1Count5V Attachment 169001701A55.pdf (203 Downloads)

myhaye Posts: 45 Rating: (0)	hello, after this counter module 24V/100KHz i introduced a new module 4DO DC24V/2A and i close with 6ES7 193-4JA00-0AA0. Itry to find what type of terminal module i need for this, but i do not find a document who explain exacly, what i must to put. if someone have another sugestion? best regards

I use it, if I have to configurate a ET200 station.

seyfeddin Posts: 4 Rating: (0)	Hello, i am using same count module and have same problem. i am opening the sw gate but internal gate status bit is always false. my terminal module is TM-E15C24-01. does it create a problem? what is the difference between TM-E15C24-01 and TM-E15S24-01. Thanks
