A
(0) The transmit data default value is set.
'I/O communication request' (Y11) is turned on.
(25) The communication status of nodes is read.
(31) The master function data consistency dedicated instruction setting status is read.
(36) The receive data is read from the master function receive data area.
(149) When M+RJ71DN91_MasterRead is normally completed, the read data is copied, and the copy is stored in each slave node area.
(159) When the communication status with the slave node (node address 1) is off, the number of communication errors is counted.
(178) When the communication status with the slave node (node address 1) is on, the receive data is stored in the data area for the slave node (node address
1).
(183) When the communication status with the slave node (node address 2) is off, the number of communication errors is counted.
(202) When the communication status with the slave node (node address 2) is on, the transmit data is created.
(209) When the communication status with the slave node (node address 4) is off, the number of communication errors is counted.
(228) (234) When the communication status with the slave node (node address 4) is on, the receive data is stored in the data area for the slave node (node
address 4), and the transmit data is created.
(249) When the communication status with the slave node (node address 3) is off, the number of communication errors is counted.
(268) When the communication status with the slave node (node address 3) is on, the receive data is stored in the data area for the slave node (node address
3).
(272) The created transmit data points are merged into one.
(297) The merged transmit data is written to the master function transmit data area.
