Shown below are the addresses of the diagnostic table (communication monitor table, etc.)
(1) Address of the communication monitor table (master mode)
The communication monitor table shows the communication status of each node using the following
bits (ON/OFF) in node addresses 0 to 63.
(ON: Normal, OFF: Abnormal)
Allocation system Fixed Free
Node address (Bit)

*1: Enter top address to system memory #304 to #307. - Page 8-12, 8-40
- The master node turns ON when it can communicate normally with all the slave stations on the scan
list table.
- Even the "even number allocation" and "allocation in order of securing empty nodes" are selected,
bits corresponding to node addresses of "not connected slave module" and "slaves without I/O
message" are always OFF.
(2) Operating status monitor table addresses (master mode)
The operation status monitor table shows the operating status of each slave station using the
following bits (ON/OFF) in node addresses 0 to 63.
(ON: Slave station is operating, OFF: Slave station is idle)
Allocation system Fixed Free
