I thank you for your support in the following consultation:
A problem in the communication of the RTU with the SCADA has appeared, and verifying with Protocol Analyzer gives me the following message:
X: Modbus function code 128 (0x80) - Unknown modbus function code - Exception Response
Remote address 128 (0x80)
X: Modbus function code 128 (0x80) - Unknown modbus function code - Exception Response
Remote address 128 (0x80)
Q: Modbus function code 3 (0x03) - Read Output Registers
Remote address 1 (0x01)
Request holding registers 4001 to 4012
What do these errors mean, and can I can solve it? Thank you for your comments.
