Faults and fixes 6ES7657-0XB00-0YH0
Problems with 6ES7657-0XB00-0YH0: does not boot, BIOS settings or date lost
An industrial PC that starts with a wrong date after a power loss or hangs in the BIOS has a flat CMOS battery (coin cell). Replace it and restore the BIOS settings (boot order, SATA mode). If it still does not boot, the storage (HDD, SSD, CompactFlash) and the power supply are the next suspects.
6ES7657-0XB00-0YH0: drops out when warm or restarts by itself
Spontaneous restarts and drop-outs after running for a while are mostly thermal: a clogged dust filter, a fan that no longer turns or dried-out thermal paste. Clean filters and fans and check the cabinet temperature. Aged capacitors in the power supply give the same picture; a refurbishment addresses both.
What do I check when replacing a 6ES7657-0XB00-0YH0?
First make an image of the old device's storage; the software and licences are on it. Choose the same product version so chipset and drivers match the image, and carry over the CompactFlash or SSD with the image where possible. Then check the licences of WinCC, PCS 7 or the machine software, as they are sometimes tied to the hardware.
Fault not fixed: replace, exchange or repair the 6ES7657-0XB00-0YH0?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6ES7657-0XB00-0YH0 new in factory packaging, with a 24-month warranty. The current lead time is shown with the condition on this page. Prefer an exchange: you get a refurbished unit straight away and return the faulty one within 14 days. Repairing your own unit is also possible: diagnosis, then a fixed price.
What information should I send for a quick diagnosis?
A photo of the rating plate (order number, product version, firmware), the exact fault code or LED state, when the fault occurs (at power-up, on enable, under load) and what you have already tried. For PLCs an export of the diagnostic buffer, for drives the parameter set. With that we can usually say the same day whether replacing, exchanging or repairing is best.
