Operation Using a Programmable Logic Controller (PLC)

Network Communications and Discrete I/O

The ProMix PD2K Automatic system does not use a Booth Control module. Instead, it uses Network Communications and has optional Discrete I/O features to drive the system remotely.

Some automation control elements of the ProMix PD2K can be driven by a discrete input or network communications. These options need to be conﬁgured at the ADM (see System Screen 5, page 71). The following features can be set to ‘Discrete’ or ‘Network’:

•Flow Control – Means of adjusting the control set point (see Flow Control Set Point below).

•Gun Trigger – Means of signaling the ProMix PD2K when the spray device is triggered.

NOTE: The Manual Override check box enables a user to operate the system before the automation (PLC) is available. Manual Override can be used to run all functions of the system if a proper gun trigger signal is provided. It is not intended to be the main mode of control. Graco recommends that Manual Override be disabled during normal operation to avoid driving the system in a way that conﬂicts with the automation sequence.

Discrete I/O

The ProMix PD2K does not supply power for Discrete I/O. A clear understanding of these inputs is necessary to properly integrate the ProMix PD2K with the PLC or networking device. Input and output connections are made at the Discrete I/O terminal strips on the Enhanced Fluid Control Module (EFCM) inside the control box.

Table 3 and Figure 2 show where discrete I/O connections are made on the ProMix PD2K.
