After the Get command is executed, the “SeaI/O Configuration” tab will display
colored labels showing the SeaI/O model number and interface type. The “Set Device
Settings” and “Change Slave ID” buttons will also be enabled for this module. In the
example shown, the module found at slave ID 247 is a SeaI/O 410 module with an
RS-485 interface.
After a successful Get operation, additional tabs may be displayed in MaxSSD,
depending on the found device model. These tabs display device I/O and allow easy
configuration for the entire SeaI/O family of devices.
The “Broadcast to Multiple SeaI/O Devices” checkbox, along with the “Set Device
Settings” button can be used to change the baud rate and parity on multiple SeaI/O
modules at once. MaxSSD broadcasts a set data rate and set parity command to all
devices on the RS-485 bus, but only those modules listening at the current baud rate
will be able to receive and respond. For example, if you have five SeaI/O modules
chained together and two are set to 9600 bps and no parity and three are set to 115.2k
bps and the PC is set to 9600 bps, only the two modules set to 9600 bps will receive
the broadcast set data rate and parity message.
NOTE: Important note regarding SeaI/O Ethernet (E-series) modules
The broadcast feature sets the Ethernet SeaI/O (E-series) module’s
TCP/IP to RS-485 translation data rate independently of the SeaI/O
module itself. Therefore, if you have an Ethernet SeaI/O module
and you set the data rate to 115.2K bps via a MaxSSD broadcast
command, both the RS-485 port and the Ethernet port will respond
thereafter to 115.2K bps, as expected. However, if you reset the
SeaI/O module by rotating the rotary switch clockwise one complete
revolution, the RS-485 port will reset to 9600 bps and no parity, but
the Ethernet port will remain unaffected. To restore
communications, broadcast another set data rate and parity
command (9600 and no parity) via MaxSSD.
