1769 Compact I/O

DeviceNet I/O Adapter Module

An I/O adapter module installed at the left end of the first bank of I/O modules interfaces these I/O modules with a DeviceNet link for communication with a DeviceNet scanner port at another location. The 1769-ADN DeviceNet I/O adapter module can interface 1, 2, or 3 banks of 1769 I/O modules for a maximum total of 30 I/O modules at a DeviceNet node. A single bank can consist of a maximum of 12 I/O modules.

The adapter supports a total of 180 words of input data and 180 words of output data from the I/O modules. The adapter supports a total of 724 words of configuration data for the I/O modules. The adapter also supports change-of-state, cyclic, and polling modes. Each bank of I/O modules must include a 1769 power supply. You connect the banks of I/O modules with 1769 expansion cables.

Note that since the MicroLogix 1500 controller and CompactLogix L20, L30, L321, L32E and L35E controller can be used with the 1769-SDN DeviceNet scanner, the 1769-ADN DeviceNet I/O adapter module can be used to interface remotely located 1769 I/O modules.
