Hide thumbs Also See for I-7530A-MR:

When the I-7530A-MR receives a valid Modbus RTU command, it

converts this command into a CAN message and transmits it into the

CAN network. Based on the same reasoning, when a CAN message is

received via the I-7530A-MR, the message will be stored in the I-7530A-

MR until being obtained by the Modbus RTU master.

2. Hardware Installation

Users need to make a hardware connection between the two I-

7530A-MR modules before the application. The details of this are

illustrated below:

Step1: Set-up the 120Ω terminator resistor of the module A and B.

Before you continue, if you have changed the settings from default

then it is necessary to open the cover for each I-7530A-MR and

re-configure their JP3 jumpers to enable them again, as shown in

below figure. However if the I-7530A-MR's still have their default

settings then it is not necessary to open and reset them because

the default configuration is enabled.
