3.2 PC Link Communication
3.2.1 Overview
PC link communication enables the UTAdvanced to communicate easily with PCs, touch
panels, and FA-M3 (PLC) UT link modules. With PC link communication, the D registers
and I relays (UTAdvanced internal registers) are read and written.
► D registers and I relays:

CAUTION
The parameters of the UTAdvanced are placed in the D registers.
If the settings of some parameters are changed, the related parameters may be
initialized.
When changing the parameter setting, configure (write) the settings in the following
orders.
1. Setup parameters
1-1 Control mode parameter (CTLM) *1
1-2 Input -related parameters *2
1-3 Output-related parameters
1-4 Other necessary parameters
2. Operation parameters
2-1 Alarm type parameters
2-2 Alarm setpoint parameters
2-3 Other necessary parameters
*1: If the setting of CTLM (control mode) is changed, the related parameters will be initialized.
UT35A/UT32A/UP35A/UM33A does not have the parameter CTLM (Control mode.)
*2: If the setting of IN (input type) is changed, the parameters related to ranges or scales such
as target setpoint etc. will be initialized.
