11BIO Link/Remote I/O Instruction (SMT-CD model only)
The SMT-CD models include the capability to link additional SMT-CD units
via the RS-485 connection terminals. The baud rate and communication format
both can be set using the Operation» Module System Set… menu selection from
the SMT Client software. They also can be set through keypad like adjacent picture.
The two bits of keypad how to decide the communication format and baud
rate like describing below.
High bit
8/N/2 Data 8bit, No Parity, 2 Stop bit.
8/E/1 Data 8bit, Even Parity, 1 Stop bit.
8/O/1 Data 8bit, Odd Parity, 1 Stop bit.
8/N/1 Data 8bit, No Parity, 1 Stop bit.
Low bit
IO Link
Up to 8 iSmart units can be linked together as the IO Link Network. Each unit runs their own logic program; In a
set of devices,
the IDs should be different between the members; the ON/OFF state of input, output points, and
Auxiliary Coils in each one can be assigned to “W Table”, see the next page for more information. There must be one
master (ID=00) and several slavers with the continuous ID number starting from 01 in the network. The master one
does not perform the IO Link function to the units with the ID behind the first broken number once the ID numbers
are not continuous. For example, the slavers’ ID are 01, 02, 04 and 05, the master just can recognize only two slave,
ID 01 and 02, the ID 04 and 05 will be skipped.
