MELSEC iQ-R Series Safety CPU Modules & Remote I/Os

(6/21/2017)

iQ-R Integrated Safety Controller
The iQ-R Integrated Safety solution delivers functionally safe machines in one platform, over one network, and using one software. It is a standard iQ-R controller with additional safety features that comply with IEC 61508 SIL3 and ISO 13849-1 PLe international safety standards. It also uses the standard iQ-R Series base units, power supplies, communication, and special function modules.


System Configuration

Network_Safety_3_b_2

iQ-R Safety CPU
Since the iQ-R Safety CPU must be used in combination with the Safety Function Module, we’ve bundled the two together as a set. To order, please add the suffix “-SET” at the end of the iQ-R Safety CPU’s part number. For example: R08SFCPU-SET.

4. he number indicates the number of files and folders (including system files and system folders) that can be created in the root directory on the condition that the number of characters in the file or folder name is 13 or less. In a subdirectory, up to 32767 folders can be created. Note that the number of storable files and folders will decrease if many folders with a long name, more than 13 characters (including an extension), are created.

Safety Function Module
The safety function module must be mounted next to the iQ-R Safety CPU module. It is included with the purchase of an iQ-R Safety CPU set, and cannot be purchased independent from the set.
