•
In case the communication is not established, right click Bridge icon and select Attributes .
•
In the field Device ID, check if the device is recognized. Select the corresponding number of the
device. See the serial number in the identification label of the MB-700 module.
•
Next download the configuration. Right click the Fieldbus1 or Bridge (MB-700) and select
Download . The configuration will be sent to the MB-700.
•
After having sent the configuration, user must change the parameter ON_APPLY of the CCCF
Block to “Apply”. This will update the configuration of the CCSM Block.
On Line Configuration
It is possible to set blocks of the MB-700 on line with the device connected to the network and
functioning. It is only necessary that user right-clicks the block and select
On Line Characterization .
User may also monitor all parameters now.
IMPORTANT
To make effective the new configuration, user must always change the parameter ON_APPLY to
Apply, otherwise this configuration will not be updated in the MB-700. User also must check which
parameters may be set and changed in the “Auto” mode because a few parameters may only be
changed in the OOS mode.
MB-700 as a TCP/IP Master
Description
MB-700 functionality in this scenario:
¾
Bypass (Serial to TCP): MB-700 works as protocol converter. In this function it converts a serial
MODBUS RTU message to TCP/IP and TCP/IP to Modbus RTU.
¾
Peer-to-peer: MB-700 can exchange data between slave Modbus devices. These slave devices
might be in different Modbus networks and even they can change data between each other.
1 - MB-700 working as Bypass (Serial to TCP)
In this scenario MB-700 does not have concentrator functionality. Thus the only two Blocks required
to be set are CCCF and RESOURCE. Several MB-700s are connected in an Ethernet. In every MB-
700 are connected several slave devices. User may set any of these controllers from the same
station. Two MB-700 are connected and the respective stations are connected through the serial
EIA-232 ports of each MB-700. The Ethernet ports connect these MB-700s to the corporate
network. Connected to this network is a third MB-700 and on it are connected the slave MODBUS
devices. MB-700 acts as a TCP/IP master establishing a bridge between workstations, local network
and MODBUS network. The great advantage given by this configuration is to allow the connection of
a MODBUS slave with several serial masters. This allows one slave to be accessible in several
points of Ethernet through MB-700.
NOTE
For this scenario, MB-700 does not support CCSM and CCCM Blocks.
