C314A0 Critical error

A critical error occurred related to IO

Try the following actions to see which resolves the issue: (A) Conduct a complete rebooting sequence, (B) Check for IO connections, (C) Update software, (D) Contact your local Universal Robots service provider for assistance

C314A5 Expected OSSD pulse were not detected on CO{unsigned}

The generated OSSD pulses on the safety output were not seen during readback

Try any of the following actions to resolve the issue: (A) Verify safety output is not connected to any power supply or another safety output, (B) Update software, (C) Contact your local Universal Robots service provider for assistance

C314A6 An unexpected OSSD pulse was detected on CO{unsigned}

An OSSD pulse was detected on the safety output readback, but was not generated by the hardware

Try any of the following actions to resolve the issue: (A) Verify safety output is not connected to ground or another safety output, (B) Update software, (C) Contact your local Universal Robots service provider for assistance

C314A7 The IO voltage is missing or below threshold

The IO voltage is missing or below the threshold, a fuse may be blown or removed

Ensure the IO Power Connector on the Safety Control Board is connected to the 24VDC and the fuse is in working condition

C314A8 The configurable safety outputs were not low when expected

The configurable safety outputs were not low when expected

Try any of the following actions to resolve the issue: (A) Verify safety output is not connected to any power supply or another safety output, (B) Update software, (C) Contact your local Universal Robots service provider for assistance

C314A11 Configurable IO circuit asserted its alert signal

Read the alert status register for specific error information

Try any of the following actions to resolve the issue: (A) Verify safety output is not connected to any power supply or another safety output, (B) Update software, (C) Contact your local Universal Robots service provider for assistance

C314A12 Could not allocate RX and/or TX buffer

The SPI DMA buffers are frequently rotated (freed and reallocated). The allocator returned a null pointer.

Try the following actions to see which resolves the issue: (A) Conduct a complete rebooting sequence, (B) Update software, (C) Contact your local Universal Robots service provider for assistance

C314A13 Configurable IO circuit reports invalid CRC or clock count error

Transmitted frames must be exactly 32 bits in length and contain a valid 8-bit CRC

Try the following actions to see which resolves the issue: (A) Conduct a complete rebooting sequence, (B) Check for ESD noise or interference on the SPI bus, (C) Update software, (D) Contact your local Universal Robots service provider for assistance

C314A18 Timed out while waiting for conversion to complete

A timeout occured while waiting for the "ADC ready" pin to assert

Try the following actions to see which resolves the issue: (A) Conduct a complete rebooting sequence, (B) Update software, (C) Contact your local Universal Robots service provider for assistance

C314A19 Timed out while waiting for a transaction to complete

A timeout occured while waiting for an "SPI transaction complete" callback

Try the following actions to see which resolves the issue: (A) Conduct a complete rebooting sequence, (B) Update software, (C) Contact your local Universal Robots service provider for assistance
