Powering Up
When first starting up the system, do not connect the Host Interface Unit to
the host. When power is turned on to the PT, either a “Connecting to host”
message or the initial screen set by the Support Tool will be displayed. The
“Connecting to host” message will be displayed if a Host Link Interface Unit,
a SYSMAC BUS Interface Unit, or a C200H Host Interface Unit is mounted.
The initial screen will be displayed if an RS-232C or RS-422A Interface Unit
is mounted.
If there is no screen data registered for the PT, or if there is an error in the
screen data that is registered, then the System Menu will be displayed
instead, with an error message at the bottom. In that case, it will be neces-
sary to initialize the memory and transmit the correct data.

Initialization
Initialize the memory in the PT using the procedure described below. This
procedure can also be used later to completely delete data from the PT. Data
will be initialized regardless of the setting for the resume function. Always be
careful not to initialize and delete essential data.

Initializing Memory
Perform the initialization if the screen memory is either SRAM or EEPROM.
Check to be sure that the screen memory is installed.
Memory initialization can be used to initialize screen memory, memory tables,
and history data. Initializing screen memory completely deletes the contents
of the screen memory, including the contents of numeral tables and text
string memory tables. Initializing memory tables overwrites numeral tables
and text string memory tables with the initial values set by the Support Tool.
Initializing the display history deletes all of the display history data.
