*Bit 2 of Time of day clock control word must be set or the PLC will not read clock values

definitions specified. Write either a 4000hex or 6000hex into the first location allocated for

the PLC time of day clock. Refer to the MODSOFT programming manual for more information

on the time of day clock usage.

☞ Note: The PLC time of day clock is read once at power up from registers 4x+1 through 4x+8.

The modules internal clock chip is synchronized with the PLC clock at this time. After

power up, the module clock is synchronized with the PLC clock at least once a day.

To configure the time of day clock in Modsoft, start the Configuration

Overview menu and tab to the Overview, Specials selections. Cursor to the

Time of Day Clock and map the first register to the second 4x register of the

module. For example, if the module is mapped to 400001-400009, map the

time of day clock to 400002-400009.
To configure the time of day clock in Concept, select the project Configurator,

then select Configure Specials. Cursor to the Time of Day Clock and map

the first register to the second 4x register of the module. For example, if the

module is mapped to 400001-400009, map the Time of Day Clock to 400002-

400009.
Either method maps the Time of Day Clock to overlay one module. If more

than one module is installed in the system, you must reserve additional

registers and use ladder to copy the Time of Day Clock values into the

additional modules 4x register set. All eight registers must be copied. For

example, if an additional module were mapped to 40010-40019, ladder would

need to be added to copy 40002-40009 to 40012-40019.
