The Model AGP-*****-CA1M/LT has a built-in CANopen master driver. By connecting the CANopen slave unit "Hybrid Terminal Block" (model: HTB-1C0DM9LP; hereafter referred to as "HTB") manufactured by Digital Electronics Corporation or a CANopen-compatible slave unit to this display unit, you can control external I/O in a remote location.
Moreover, by attaching an EX module to the HTB, I/O can be extended.
For each display unit, you can construct an open network, connecting a maximum 63 HTB or CANopen compatible slave units. A maximum of seven EX modules can be attached to each HTB unit.

CANopen Master Driver
Uses DS301V4.02, DSP302V3.2, and DS405V2.0 profiles. DS301 is a profile used for the application layer and for communication. DSP302 is a framework for the CANopen Manager and programmable CANopen devices. DS405V2.0 is a profile for IEC61131-3 programmable devices.
Supports 11 bit COB-ID (CAN2.0A). Does not support 29 bit COB-ID (CAN2.0B).
For HTB, the communication is carried out in PDO packet units. The entire system can support up to 252 units of RxPDO and up to 252 units of TxPDO. When mapping to TPDO4~ and RPDO4~, together with all the slave settings, it is limited to a maximum of 64 units.
Does not support flying master*1.
Network configuration is saved in a concise DCF file*2. This concise DCF file is transferred to the display unit when transferring a project.
*1 Flying Master is a feature that allows the flying master to dynamically determine the master in a network when there are multiple devices that can used as the CANopen master.
*2 Concise DCF is a device setting file in binary data format. The CANopen network is configured by downloading this data to the NMT master. NMT master is a feature that controls the actions of a slave node. Only one exists in any CANopen network; the node with this NMT master feature becomes the CANopen master.)
