They are using Promethane
Demo was showed to the customer for RS232 data- Getting accurate from the weighing scale and was posted to the Eremos Cloud Server through 4G.
For RS485 data- We are not sure about the address mapping properly,through the usb to rs485 device we can able to send the address and response but through SAML21 device we cant get the response shows timeout error.
Suggestion:
Venu sir:
As per the suggestion of Venu sir,We showed the RS232 data to the Customer and the RS485 data needs to be validate.
Raised the Query to the Promethean Power system for 8 Relay Board rs485 port and address mapping.
Sir shared one document regarding the address mapping.
Thomas Sir:
Thomas sir suggested to conduct the test as follows
1.Connect Tracker, Promethean device and 485-USB converter in the 485 bus. observe traffic in teraterm.
2.Please setup this in lab(use modbus tool in place of Promethean device) and observe.
