SUPPORTED DEVICES AND ACCESSIBLE
RANGES
This chapter explains the supported modules and accessible modules.
2.1

Supported Devices

Communications using the MC protocol can be performed as an external device if a device can incorporate application
programs and send/receive data using the control procedures of the MC protocol.
This manual explains MC protocol communication when connecting the devices shown below and external devices.
Type
Serial communication module
Ethernet interface module

Accessible Range and Accessible Modules

A CPU module and other station on the network can be accessed via a supported device.
Accessible range
The following devices are accessible.
• Supported devices that are connected to the external device directly (connected station)
• Other stations on the same network with the supported devices
• Other stations on the other network that are connected to other station in the same network with the supported device.
*1 Other station on which network No. and station No. is set, and a multidrop connection station can be accessed.
The accessible range differs in types (frames) of a message format.
The following figure shows the maximum range that can be accessed.
External device
For the accessible range of each message, refer to the following sections.
Message formats of serial communication modules
• Page 45 Accessible range of 4C frame
• Page 46 Accessible range of 3C frame
• Page 46 Accessible range of 2C frame
• Page 47 Accessible range of 1C frame
For details on the accessible range of programmable controllers of other stations on a network system, refer to the manual for
the network system used.
The multiple CPU system is supported. For details on the multiple CPU system, refer to the following section.
