[3] Error status flag
Shows the error information for each node
*1: Addresses +100 to 137(8) are offset addresses calculated from the top address that is stored in the
parameter at addresses 30 to 32(8)).
*2: 1 to 254 are express node number. By turning the bits in these addresses on and off, the participat-
ing status of each node can be represented.
* When other nodes are allocated by controllers from other manufacturers, follow the specifications
for their PCs.
