× × ○ ○ OFF – – R OFF *SM1592 The number of polling cycles in the PLC Link is incorrect. ○ ○ × × OFF – – R OFF *SM1593 Standard Modbus communication protocol is used in the PLC Link when SM1593 is OFF, whereas AH communication protocol is used in the PLC Link when SM1593 is ON. ○ ○ × × – – – R/W OFF *SM1594 The slaves are automatically detected in the PLC Link in the current environment. Only when the PLC Link is in the stop mode can SM1594 be used. OFF: The detection is complete or the PLC is waiting to detect the slaves. ON: The PLC is detecting the slaves. ○ ○ × × OFF – – R/W OFF Automatically detecting slaves for the Modbus connection of COM1 in the current environment:
Only when the Modbus connection of COM1 stops can SM1594 be used. OFF: The detection of slaves is complete or the PLC is waiting to detect slaves. (default value) ON: The PLC is detecting slaves. × × ○ ○ OFF – – R/W OFF *SM1595 The slave IDs are assigned by users when SM1595 is ON, whereas they are assigned automatically when SM1595 is ○ ○ ○ ○ – – – R/W OFF
