Modbus Commands

Set Modbus Gateway

key-exchange
The type of key to exchange for the encryption format:
zAny—Any key exchange that is valid is used (this does not, however, include ADH
keys).
zRSA—This is an RSA key exchange using an RSA key and certificate.
zEDH-RSA—This is an EDH key exchange using an RSA key and certificate.
zEDH-DSS—This is an EDH key exchange using a DSA key and certificate.
zADH—This is an anonymous key exchange which does not require a private key
or certificate. Choose this key if you do not want to authenticate the peer device,
but you want the data encrypted on the SSL/TLS connection.
The default is Any.
hmac
Select the key-hashing for message authentication method for your encryption type:
zAny
zMD5
zSHA1
The default is Any.

User Level Admin
Syntax set modbus gateway [addr-mode embedded|re-mapped]
[broadcast on|off] [char-timeout <number>]
[req-next-delay <number>] [exceptions on|off]
[idle-timer <number>] [mess-timeout <number>]
[port <TCP/UDP_port>] [req-queuing on|off]

Options addr-mode
Determines if the original UID address will be embedded in the transmission header or
if a specified (remapped) UID will be embedded in the transmission header.
broadcast
When enabled, a UID of 0 (zero) indicates that the message will be broadcast to all
Modbus Slaves. The default is Off.
char-timeout
Used in conjunction with the Modbus RTU protocol, specifies how long to wait, in
milliseconds, after a character to determine the end of frame. The default is 30 ms.
