Delta Electronics RTU-EN01 BR#11 Communication Time-out ms, BR#12 Communication Delay Time ms

Modbus TCP Remote I/O Communication Module RTU-EN01

Code	Indication		How to correct
F0	Returning to default setting	--
F1	RTU-EN01 being powered	--
F2	Power supply in low voltage	Check if the power supply of the module works normally.
		1.	Check if the settings of smart PLC are incorrect.
F3	Internal error. Manufacturing error.	2.	Re-power RTU-EN01. If the error still exists, try step 3.
		3. Reset RTU-EN01. If the error still exists, send the module back to
			the manufacturer for repair.
F5	Network connection error	Check if RTU-EN01 is connected normally to the network.
F6	Insufficient TCP connection	Check if the number of connected modules exceeds the maximum.
F7	RS-485 setting error	Check if the RS-485 communication format is correct.
		1.	DHCP request failure.
		2.	IP setting error.
F8	IP setting error	3.	MASK setting error.
		4.	Gateway does not exist in the same subnet.
		5.	Returning to default setting.
		Check if the configuration of the right-side module has been modified. If
F9	Right-side module error	the error still exists, check if the number of I/O points exceeds the
		maximum and whether the there are more than 8 analog I/O modules
		connected.
04	Slave error	1.	Check if RTU-EN01 and RS-485 is connected normally.
		2. Check if the series transmission speed is consistent with that of other
0b	No response from station
			nodes on the network.

BR#11: Communication Time-out (ms)

Explanations:

For setting up the communication time-out. Default = 5,000ms. For example, if you wish to set up the communication time-out to 7 seconds manually, write 7000 to BR#11. Range: 5 ~ 65,535.

BR#12: Communication Delay Time (ms)

Explanations:

For setting up the minimum interval time between every Modbus command. Default = 0ms. For example, if you wish to set up the communication delay time to 100ms manually, write 100 into BR#12. Range: 0 ~ 65,535.

BR#13: TCP Connection Idle Time (s)

Explanations:

For setting up the TCP connection idle time. Default = 30 seconds. For example, if you wish to set up the idle time to 7 seconds manually, write 7 into BR#13. Range: 5 ~ 65,535.

BR#23: Number of Analog I/O Modules

Explanations:

Read the number of right-side modules from BR#23. Max. 8.

BR#24 ~ #31: ID of the 1s t ~ 8t h Analog I/O Module

Explanations:

Read the ID of the 1st ~ 8th analog I/O modules from BR#24 ~ BR#31.
