14.2 Selecting Memory Card Capacity

Select a memory card capacity according to the types and sizes of files to be stored in the
memory card. The sizes of files are calculated using the formulas presented below.

• Setting with GX Developer
The comment data size of 1 device is as follows:
10250 a + 40 b + 10 (Quotient of (No. of devices / 256) is substituted for a and the remainder for b.)
• Setting with SW IVD-GPPQ
Although the size varies depending on EMS capacity, it is equivalent to or less than the size obtained in the above DX
Developer case.

• According to the items set in the added trace information on the trace device setting screen, the following values are
added forN1 to N3.
(Refer to Section 8.5 (2) (b))
N1: When setting time, "4" is added.
N2: When setting step No., "10" is added.
N3: When setting the program name, "8" is added.

*1 "Device types" represents the number of registered device names.
For example, if D, W, and T are registered, it is 3.
*2 "Device ranges" represents the number of registered range settings.
*3 These files can be transferred from the memory card to the built-in RAM in the boot operation.
*4 The total number of setting ranges is the total number of types of the devices that are set as
local devices.
*5 Decimal fraction of "number of bit device points/16" is rounded up.
