  1. Hi kratmel, Unitronics PLCs are not computers, and supporting FAT32 formatted SD cards up to 32 GB. Supported FAT32 File system is limited to 1 primary partition. For example: Siemens PLCs: S7-1200 CPU only supports the memory cards that have been preformatted by Siemens manufacturer, whose order numbers are shown in the table below: Order number Capacity 6ES7 954-8LF01-0AA0 24MB 6ES7954-8LC01-0AA0 4MB 6ES7 954-8LB01-0AA0 2MB Table 1: Memory card information If SIMATIC memory card is reformatted by Windows formatting program, CPU will not be able to use this reformatted memory card. At present, S7-1200 still cannot help the memory card realize such advanced functions as recipe and data archiving. https://support.industry.siemens.com/cs/document/87133851/usage-of-s7-1200-memory-card?dti=0&lc=en-WW ABB AC500 supporting 512 MB SD cards in FAT16 format (SD card may be 2 GB formatted to FAT16, and MUST BE SLOW). https://forum-controlsystems.abb.com/360488/Using-aftermarket-SD-card-with-AC500 MC502 supporting 2 GB and ABB recommends to use SD cards, supplied by ABB. Allen-Bradley recommends to use only Allen-Bradley SAD cards 1GB or 2GB capacity, formatted to FAT16 file system. And there are many other restrictions. https://literature.rockwellautomation.com/idc/groups/literature/documents/ap/logix-ap007_-en-p.pdf So you clearly can see Unitronics PLCs advantages of SD cards use. B.R.
  2. All right, SD Tools will be modified to inform operator about SD card supported/not supported size. SD card technology allow to manufacture SD cards of big capacity, but embedded devices are limited to FAT32 file system with all its limitations. B.R.
  3. This set comprise 2 parts (and it is for Cisco Routers): 1. USB to Serial converter. 2. RS232 D-type to RJ45 8p8c). Unitronics use 6p4c or 6p6c connector. We recommend to contact PLC seller and obtain 2 cables: 1. USB to Serial Adapter (prolific chip based). 2. Serial cable and adapter (come in the kit RS232-CB1). RS232-CB1 include MJ10-22-CS25 (DB9 to RJ11 adapter) and 4 wires cross-crimped phone cable.
  4. Hi krolikbest, Set Retry=0 and minimum reasonable timeout. B.R.
  5. Any check box for power-up write power-up value to destination, either Timer or MI, etc. When check-box not checked, then last value before power-off is stored (battery backup memory). B.R.
  6. There is no such function for array. You can write UDFB to do this.
  7. Hi Scott59 I recommend you to purshase 16 GB SD card. 32GB can be formatted by Windows, but there is a problem to gormat it from SD Card Tools. If you already purshased it - format it to FAT32 and copy all firectories from fresh formatted SD card of 16, 8, or other capacity, less than 32 GB. B.R.
