FUNCTIONS & FEATURES

DL30 is used in combination with an installation base (model: R30BS) and I/O modules (Remote I/O R30 series)
■ DL30
•Collection and recording of input data, and transmission of output data
DL30 collects data from I/O modules via the internal bus of the installation base, and records the data to the internal memory and to an SD card;
connects with remote I/O modules using Modbus/TCP via Ethernet, and collects and records input data of the remote I/O modules;
connects with Mitsubishi programmable-controller MELSEC via SLMP to access data of the CPU of MELSEC; and
outputs an alarm to an output module according to the preset alarm level.
• Web server
DL30 works as a web server to display collected data on the web browser of a PC or tablet.
Various setting and operation can be performed through the web browser.
• Internal power
Internal power required for DL30 and I/O modules is generated from supplied power.
■ I/O MODULES
An output module outputs data received through the internal bus as discrete outputs; and outputs discrete input data and A/D converted analog input values to the internal bus. (Refer to the specification of each R30 I/O module for details.)
■ INSTALLATION BASE
The base for mounting modules thereon incorporates PWB for internal power and the internal bus. (Refer to the specification of R30BS)
