pressed. The MB/LCL option is useful if GDA-1600s are being cascaded from and HMI
or other Modbus master. A short time delay between reset of remote RTUs and the
primary GDA-1600 may occur since remote resets are processed first.
IMPORTANT! ALL MODBUS 2001 COILS ARE WRITTEN BY THIS

3.3.5 Eight / Sixteen Channel Modes
The system menu allows for setting of the GDA-1600 controller to accept either 8 or 16
channels. If 8 channels are selected by this menu they are channels 1-8 and 9-16 become
disabled. One way GDA-1600 cost is kept low is Input / Output option PCBs are
arranged into groups of 8 channels. Therefore, users with less than 9 channels require
only 1 PCB and do not pay for I/O hardware for 16 channels. If more than 8 channels are
needed a second I/O option PCB may be required.

3.3.6 Sensor Information
Sensor Info is available when at least one channel has Sensor Life activated in the
Marker menu (see section 3.2.4.2). The Sensor Info screen displays each channel’s
sensor status as illustrated in Figure 3.16. Channels with Sensor Life disabled indicate
Option Disabled above the corresponding empty bar-graph. If Sensor Life is enabled,
the channel will have its Measurement Name above the bar, or, an empty bar with a
Cal
Required label. Cal Required indicates no Calibration Marker value has been
received by the GDA-1600.
