Linear encoder: Novotechnik TMI-0300-002-222-101, resolution 0.005 mm / 25-bit / Gray / SSI is connected to the stationET200S 1SSI, 6ES7138-4BD03-0AB0. Parameters Device-specific parameters are as follows: Group diagnosis-enable capture-synchronous sensor type-SSI-25bit gray / dual converter-gray transmission rate-500Khz parity-none monoflop time-32us standardization-off number of trailing bits -13 direction of rot / reversal-on total steps of encoder -33554432 latch-inactive comparator1-inactive comparator2-inactive sensor sampling rate -0.5 KHz vital signs-disable When the power station and the module is lit all the time 1SSI error SF. questions: 1. Does the general module 1SSI linear encoders can be connected? 2. which parameters are set in the Properties -> Parameter Assigment -> Device-specific parameters, to eliminate the error? 3. particularly in the setting number of trailing bits, how many bits are set?

But I'm still confused by that number of trailing bits is not greater than 15 and for 25-bit probably to number of trailing bits -25??? If so, it seems to connect 25-bit encoder to 1SSI impossible ... Does anyone have any ideas on this? And here's a screenshot error Attachment ScreenShot_Error.jpg (142 Downloads)
