Example 3: T10 Current Value 484 Mode
Find the MODBUS address to obtain the
PLC Address (Dec.) + Mode Address
current value from Timer T10. TA10 = 8 decimal
1. Find Timer Current Values in the table. 8 + 3001
=
2. Convert T10 into decimal (8).
3. Add the MODBUS starting address for the mode (3001).
Example 4: C54 584/984 Mode
Find the MODBUS address for Control Relay C54.
PLC Addr. (Dec.) + Start A Mode
1. Find Control Relays in the table. C54 = 44 decimal
2. Convert C54 into decimal (44). 44 + 3072 + 1
=
3. Add the starting address for the range (3072).
4. Add the MODBUS address for the mode (1).
Network Master Operation
This section describes how the DL06 can communicate on a MODBUS or
Direct
NET
network as a master. For MODBUS networks, it uses the MODBUS RTU protocol, which
must be interpreted by all the slaves on the network. Both MODBUS and
Direct
Net are single
master/multiple slave networks. The master is the only member of the network that can initiate
requests on the network. This section teaches you how to design the required ladder logic for
network master operation.
