CS1 series CPU type : CS1G/H-CPUjj-EV1

PC Setup

When connecting to a CS1 series CPU, set the following communication condi- tions for the PC Setup area, in accordance with the communication port to be used.

When using the built-in RS-232C port of CS1G/H

Word #	Writing Value	Settings
160	8200	NT link (1:N) mode
161	000A	Communications baud rate (high-speed)
166	000j	j = The largest model number of the
		connected PT (0 – 7)
When using the peripheral port of CS1G/H

Word #	Writing Value	Settings
144	8200	NT link (1:N) mode
145	000A	Communications baud rate (high-speed)
150	000j	j = The largest model number of the
		connected PT (0 – 7)

When connecting PTs with model numbers 0, 2, 3, 4, and 5 to the built-in RS-232C port, for example, set the value 8200 Hex to word 160, 000A Hex to word 161, and 0005 Hex to word 166.

Either set PC Setup directly from a Programming Device (Programming Con- sole), or transmit the PC Setup made at a Programming Device (CX-Program- mer) to the CPU.

For details on PC Setup, refer to the SYSMAC CS1-series Operation Manual (W339-E1-j).

Reference: When using the CX-Programmer to set the high-speed 1:N NT Link, set the com- munications baud rate to 115,200 bps.
