Register description in TPDO_8 is similar to TPDO_4 with following interpretation:
Information Register: every state of each module is "anded" in this PDO and shows the summary of the system
Warning Register: bit 15…3 of every module is "ored"; bit 2..0 is calculated by master
Error Register: every state of each module is "ored" in this PDO and shows the summary of the system
