Detailed Description

Bits for internal indication of the error condition. Each error condition is specified by unique index from 0x00 up to 0xFF.

If specific error occurs in the stack or in the application, CO_errorReport() sets specific bit in the errorStatusBit variable from CO_EM_t. If bit was already set, function returns without any action. Otherwise it prepares emergency message.

Maximum size (in bits) of the errorStatusBit variable is specified by CO_CONFIG_EM_ERR_STATUS_BITS_COUNT (set to 10*8 bits by default). Stack uses first 6 bytes. Additional 4 bytes are pre-defined for manufacturer or device specific error indications, by default.

CO_EM_MANUFACTURER_START

#define CO_EM_MANUFACTURER_START   0x30U
